There are two grammatical genders in Danish: common and neuter. All nouns are mostly arbitrarily divided into these two classes. The singular indefinite article (a/an in English) for common nouns is en and for neuter nouns is et. They are often informally called n-words and t-words.

En dreng. A boy.

Et fængsel. A jail.

Unlike English, singular definite nouns in Danish are rendered by placing the indefinite article as a suffix at the end of the noun.

Drengen. The boy.

Fængslet. The jail.

The articles and suffixes for plural nouns are more complex. The following table shows the various inflections of articles for regular Danish nouns in both noun classes.

Gender Singular Plural Meaning
Indefinite Definite Indefinite Definite
Common en dreng
en sag
en kvinde
en ske
Neuter et fængsel
et æble
et lyn
"flash of lightning"

As the table above indicates, there is a certain degree of predictability of the plural form based on the gender and the number of syllables in a word. However, even among regular nouns, the choice between -er and -e for common gender nouns is not predictable in monosyllables and one can only generalize that borrowings tend to take -er. Furthermore, there are many irregular nouns, as exemplified below.

Note that if the final syllable ends in unstressed -e, -el, -en, or in some cases -er, the e will disappear if a grammatic ending starting with an e is added. E.g. the declension of "fængsel" above is quite regular.

There are many nouns with irregular plurals. Here are some typical examples:

Gender Singular Plural Meaning
Indefinite Definite Indefinite Definite
Common en mand
en bonde
en drink
en sten
en risiko
Neuter et barn
et hus
et våben

Some have the "wrong" regular form, some have vowel change with or without a suffix, and some are foreign words using their native plurals. In all cases, it is only the plural indefinite that is irregular. Singular definite always just adds -en or -et. Plural definite adds -ne to the indefinite if it has a standard plural suffix, -ene if not.

Grammatical case

There are no case declensions in Danish nouns except the genitive, which is normally applied as an -s ending, or simply with an apostrophe when the noun ends with an s already (also if the word ends in x or z). Pigens hus ("the girl's house"); et hus' beboere ("the inhabitants of a house"). Thus, one does not distinguish between persons and things in the genitive. The order of the genitive and the governed word is always the same as in English.

When the noun governed by the genitive can be considered part of the governing noun physically, the genitive is often replaced by a prepositional phrase, e.g. låget på spanden "the lid on the bucket", bagsiden af huset "the back of the house" rather than spandens låg, husets bagside, which are not incorrect but more formal, and less informative.

Older case forms exist as relics in phrases like i live "alive" (liv = "life"), på tide "about time" (tid = "time"), på fode "on his foot" (fod = "foot"). Similarly, the genitive is used in certain fossilised prepositional phrases (with til "to"): til fods "on foot", til vands/søs "by water/sea", gå til hånde "assist" (hånde being an old genitive plural of hånd "hand", now replaced by hænder).


The indefinite article, en, et, is prepositive as in all European languages that have an indefinite article, and the origin of the word is the same as in the other Germanic languages, namely the numeral én, ét "one" . There is no indefinite article in the plural.

The definite article, -en, -et, -(e)ne, is postpositive as in the other Scandinavian languages save the West Jutlandic dialect of Danish, which has the prepositive æ (inflexible). The postpositive article comes from an old pronoun, Old Norse inn, "that", related to English yon and German jener . The point of departure may be expressions like ormr inn langi > ormrinn langi "the long serpent". Yet, Danish only uses the postpositive article when the noun does not carry an attributive adjective or a genitive, while otherwise a prepositive den, det, de is used instead (whereas both Norwegian and Swedish use the prepositive and the postpositive articles at the same time in such cases):

1) Since the 1970s, the polite form De (cf. German Sie) is no longer the normal form of addressing adult strangers. It is only used in formal letters or when addressing the royal family. It is sometimes used by shop assistants and waiters to flatter their customers. As a general rule, one can use du almost in every situation without offending anyone.

2) The reflexive pronoun is used when the object or possessive is identical to the grammatical subject of the sentence: han slog sin kone ihjel "he killed his (own) wife" ~ han slog hans kone ihjel "he killed his (somebody else's) wife". It is also used when referring to the subject of an infinite nexus, e.g. an accusative with infinitive: Rødhætte bad jægeren hilse sin kone "Little Red Riding Hood asked the hunter to greet his wife", where sin refers to the hunter. This difference is often not observed by Jutlandic speakers.

3) Vores is the only form normally used in current spoken language; vor, vort and vore are more archaic, and perceived as formal or solemn.


In Modern Danish the verb has nine distinct forms, as shown in the chart below.

Non-finite forms
Active forms Passive forms
Infinitive (at) vente to wait/expect (at) ventes, (at) blive ventet to be expected
Verbal noun venten a waiting
Present participle ventende waiting/expecting
Past participle (har) ventet have waited/expected (var) ventet was expected
Finite forms
Present tense venter wait(s)/expect(s) ventes, bliver ventet am/is/are expected
Past tense ventede waited/expected ventedes, blev ventet was/were expected
Imperative vent wait/expect bliv ventet be expected

Person and number

Verbs do not vary according to person or number: jeg venter, du venter, han, hun, den, det venter, vi venter, I venter, de venter. However, until the beginning of the twentieth century, it was normal to inflect the present tense in number in educated prose. There existed also a special plural form in the imperative. These forms are not used anymore, but can be found in older prose:

weak verbs strong verbs
Singular Plural Singular Plural
Present venter vente wait(s) tager tage take(s)
Past ventede ventede waited tog toge took
Imperative vent! venter! wait tag! tager! take

For example, Søger, saa skulle I finde "Seek, and ye shall find" (Matthew 7:7); in the 1992 translation Søg, så skal I finde.


Like in other Germanic languages, the conjugation of verb tenses is divided into two groups: The first group, the so-called weak verbs, indicates the past tense by adding the suffixes -ede or -te. The second, called strong verbs, forms the past tense with a zero ending and, in most cases, certain vowel changes.

The future tense is formed with the modals verbs vil or skal and the infinitive, e.g. tror du, det vil regne, "do you think it's going to rain", vi skal nok komme igen i morgen, "we'll come again tomorrow". Often the present tense is also used as future, only with the addition of a time specification i morgen køber han en bil, "tomorrow he'll buy a car".

In the perfect, the word har ("have, has") is placed before the past participle: han har købt en bil, "he has bought a car". In certain words implying a movement, however, er ("am, are, is") is used instead: han er gået sin vej, "he has gone" (like German er ist gegangen or French il est allé). In such cases har is used for the activity, while er is used if the result is what is interesting. Han har rejst meget, "he has traveled a lot". Han er rejst, "he is gone", he is not here anymore.

Similarly, the pluperfect is formed with havde or var: han havde købt en bil, han var gået sin vej. NB. The perfect is used in many cases where English would have a simple preterite.


In Danish, there are two finite moods, indicative and imperative. Depending on interpretation, there may also be an optative.

  1. The indicative mood is used everywhere, unless the imperative or optative is required.
  2. The imperative is used in commands: "Kør langsomt!" (Drive slowly!), "Kom her!" (Come here!). (The imperative is the stem of the verb.)
  3. The optative is rare and used only in archaic or poetic constructions. It's probably more correct to describe these as elliptical constructions leaving out a modal and just retaining an infinitive, e.g. "Gud være lovet!" (God be praised!), "Kongen længe leve!" (Long live the king!) -- completely analogous to the English use).

In short, Danish morphology offers very little in moods. Just like English, Danish depends on tense and modals to express modes.

Example: Where a language with an explicit subjunctive mood (such as German, Spanish, or Icelandic) would use that mood in hypothetical statements, Danish uses a strategy similar to that of English. Compare:

a. Real, or at least possibly real, situation in present time: Hvis Peter køber kage, laver Anne kaffe. "If Peter buys [some] cake, Anne makes coffee." Here, the present indicative is used.

b. Real, or at least possibly real, situation in past time: Hvis Peter købte kage, lavede Anne kaffe. "If Peter bought [some] cake, Anne made coffee." Here, the past indicative is used.

c. Unreal situation in present time: Hvis Peter købte kage, lavede Anne kaffe. "If Peter bought [some] cake, Anne made coffee." (Implying: But Peter doesn't actually buy any cake, so Anne doesn't make coffee—making the whole statement hypothetical.) Here, the past indicative is used.

d1. Unreal situation in past time: Hvis Peter havde købt kage, havde Anne lavet kaffe. "If Peter had bought [some] cake, Anne had made coffee." (Implying that Peter didn't actually buy any cake and so Anne didn't make coffee—making the whole statement hypothetical.) Here, the pluperfect indicative is used.

A language with a full subjunctive mood, the way it typically works in Indo-European languages, would translate cases a. and b. with indicative forms of the verb, and case c. and d. with subjunctive forms. In the hypothetical cases (c. and d.), Danish and English creates distance from reality by "moving the tense one step back". Although these sentences do work, however, it would be normal in Danish as well as in English, to further stress the irreality by adding a modal. So that, instead of either example c. or d1, Danish and English would add "ville/would" in the main sentence, creating what may be considered a periphrastic subjunctive:

d2. Unreal situation in past time: Hvis Peter havde købt kage, ville Anne have lavet kaffe. "If Peter had bought [some] cake, Anne would have made coffee."

(As will be seen from the examples, Danish, unlike English, switches from the normal subject-verb word order to verb-subject when a main clause follows a subordinate clause, but that's always the case and has nothing to do with the mood of the sentence. See V2 word order.)


Like the other Scandinavian languages, Danish has a special inflection for the passive voice with the suffix -s, which is historically a reduced enclitic form of the reflexive pronoun sig ("himself, herself, itself, themselves"), e.g. han kalder sig "he calls himself" > han kaldes "he is called".

Danish has a competing periphrastic form of the passive formed with the verb blive ("to remain, to become").

In addition to the proper passive constructions, the passive also denotes:

  1. a vi ses på onsdag "we'll see each other on Wednesday", I må ikke slås "you must not fight" (literally "beat each other").
  2. an intransitive form (a lexicalised s-passive): der findes / fandtes mange grunde til at komme "there are / were many reasons why one should come" (literally: "are / were found").
  3. an impersonal form: der kæmpes / bliver kæmpet om pladserne "there is a struggle for the seats".

In the preterite, the periphrastic form is preferred in non-formal speech except in reciprocal and impersonal passives: de sås ofte "they often saw each other", der fandtes en lov imod det "there was a law against it" (but real passive: de blev set af politiet "they were seen by the police", der blev fundet en bombe "a bomb was found").

The s-form of the verb can also imply habitual or repetitive action, e.g. bilen vaskes "the car is washed" (regularly) vs. bilen bliver vasket "the car is (being) washed" (right now, soon, next week, etc.)

The s-passive of the perfect participle is regular in Swedish both in the real passive and in other functions, e.g. vårt företag har funnits sedan 1955 "our company has existed since 1955", bilen har setts ute på Stockholms gator "the car has been seen in the streets of S." In Danish, the real passive has only periphrastic forms in the perfect: bilen er blevet set ude på Stockholms gader. In the lexicalised and reciprocal passives, on the other hand, we find a combination of the verb have and the s-passive preterite: e.g. mødtes "have met", har fandtes "have existed" etc. (but strangely enough, the irregular har set(e)s "have seen each other" is much more common than har sås, which is considered substandard).

Present participles

The present participle is used to a much lesser extent than in English. The dangling participle, a characteristic feature of English, is not used in Danish. Instead Danish uses subordinate or coordinate clauses with a finite verb, e.g. eftersom han var konge, var det ham, der måtte bestemme, "Being the king, he had the last word". The present participle is used in two circumstances:

  1. as an attributive adjective: en dræbende tavshed, "a boring (lit. killing) silence", en galoperende inflation, "a runaway inflation", hendes rødmende kinder, "her blushing cheeks".
  2. adverbially with verbs of movement: han gik syngende ned ad gaden, "he walked down the street singing"

If the present participle carries an object or an adverb, the two words are normally treated as a compound orthographically and prosodically: et menneskeædende uhyre, "a man-eating monster", en hurtig(t)løbende bold, "a fast(-going) ball", fodbold- og kvindeelskende mænd, "men loving football and women".

Past participles

The past participle is used primarily in the periphrastic constructions of the passive (with blive) and the perfect (with være). It is often used in dangling constructions in the solemn prose style: Således oplyst(e) kan vi skride til afstemning, "Now being informed, we can take a vote", han tog, opfyldt af had til tyrannen, ivrig del i forberedelserne til revolutionen, "filled with hatred of the tyrant, he participated eagerly in the preparations for the revolution".

The past participle of the weak verbs has the ending -et or -t. The past participle of the strong verbs originally had the ending -en, neuter -et, but the common form is now restricted to the use as an adjective (e.g. en bunden opgave), and it has not been preserved in all verbs. When it is combined with er and har to form passive and perfect constructions, the neuter form, which happens to be identical to the ending of the weak verbs, is used. In the Jutlandic dialects, -en is frequently used in such constructions.

As to the voice of the past participle, it is passive if the verb is transitive, and active if it is intransitive.

Infinitive and verbal nouns

The infinitive may be defined as a verb form that is equivalent to a noun syntactically. The Danish infinitive may be used as the subject or object of a verb like in English: at rejse er at leve "to travel is to live", jeg elsker at spise kartofler "I love to eat potatoes". Furthermore, the Danish infinitive may also be governed by a preposition (where English normally has the gerund): han tog livet af sig ved at springe ud af et vindue "he killed himself by jumping out of a window".

The infinitive normally has the marker at, pronounced ɑd̥ or in normal speech ʌ, thereby being homonymous with the conjunction og "and", with which it is sometimes confused in spelling. The bare infinitive is used after the modal verbs kunne, ville, skulle, måtte, turde, burde.

A rarer form is the verbal noun with the ending -en (not to be confused with the definite article) which is used when the infinitive carries a pronoun, an indefinite article or an adjective: hans evindelige skrigen var enerverende, "his never-ending crying was enervating", der var en løben og råben på gangene, "people ran and cried in the hall". This use has a connotation of something habitual and is often used in a negative sense. It is used in formal information like Henstillen af cykler forbudt, "It is prohibited to leave your bike here." Whereas the infinitive is accompanied with adjectives in the neuter (det er svært at flyve, "it is difficult to fly"), the verbal noun governs the common gender. Due to the rarity of this form, Danes often mistakenly write Henstilling af cykler forbudt (lit. "Recommendation of bikes prohibited") instead, using a more familiar word form.

Verbal nouns like viden "knowledge" (literally: "knowing") or kunnen "ability" (literally: "being able") have become lexicalised due to the influence of German (Wissen, Können). Like the proper verbal noun, these forms have no plural, and they cannot carry the definite article; so, when English has the knowledge, Danish must use a pronoun or a circumlocution: e.g. hans viden, denne viden, den viden man havde.

Danish has various suffixes for turning a verb into a real noun:

  • the suffix -(n)ing: hængning "hanging" (: hænge), samling "collection" (: samle). The suffix, which is still productive, is related to the German -(n)ung and the English -ing. Words with this suffix belong to the common (originally feminine) gender. The variant without -n- is used after stems ending in n, nd, r and consonant + l.
  • the suffix -else: bekræftelse "confirmation" (: bekræfte). The suffix, which is still productive, takes the common gender.
  • the suffix -sel: fængsel "jail" (: fange), fødsel "birth" (: føde"). The suffix is used to form both concrete nouns (in the neuter) and abstract nouns (in the common).
  • the verbal stem with no ending: fald "fall" (: falde), tab "loss" (: tabe), kast "throw" (: kaste), håb "hope" (: håbe), normally as a neuter noun.
  • the verbal stem with some change of vowel or consonant: gang "walk(ing)" (: ), stand "state" (: stå), sang "song" (: synge), dåb "baptism" (: døbe). They normally have the common gender.
  • the suffix -(e)st: fangst "catching" (: fange), ankomst "arrival" (: ankomme), hyldest "ovation" (: hylde). The type takes the common gender.
  • the suffix -tion, -sion: funktion "function" (: fungere), korrektion "correction" (: korrigere), eksplosion "explosion" (: eksplodere). This type is restricted to stems of Latin origin (which normally have the suffix -ere in the verbal forms, cf. German -ieren). They take the common gender.
  • the suffix "-n": "råben" "shouting" (: "råbe"), "løben" "running" (: "løbe"). Takes the common gender.

Vigesimal system

Counting above forty is in part based on a base 20 number system, called vigesimal: halvtred-s(inds-tyve) = 2½ x 20, tre-s(inds-tyve) = 3 x 20, halvfjerd-s(inds-tyve) = 3½ x 20, fir-s(inds-tyve) = 4 x 20, halvfem-s(inds-tyve) = 4½ x 20 (halvtredje, halvfjerde and halvfemte (lit. "halfthird", "halffourth" and halffifth") being old words for 2½, 3½ and 4½). This is unlike Swedish and Norwegian, both of which use a decimal system.

The word fyrre / fyrretyve = "40" does not belong to the vigesimal system. The optional second part of the word is not the number tyve, "20", but an old plural of ti, "ten" (like in English forty, German vierzig); the first part is a variant of the number fire, "four". Similarly, tredive is a compound of tre, "three", and a weakened form of the old plural of ti, "ten".

Vigesimal systems are known in several European languages: French, Breton, Welsh, Albanian, and Basque. Some scholars speculate that the system belongs to an "Old European" (i.e. pre-Indo-European) substratum, whereas others argue that the system is a recent innovation of the Middle Ages. See Vigesimal.

Sequence of numbers

The ones are placed before the tens with an intervening og ("and"): toogfyrre (42), seksoghalvfjers (76). The ones and the tens are placed after the hundreds with an optional og: to hundred (og) femoghalvfjers. This system is similar to that of German and Dutch (zweiundvierzig, zwei Hundert fünfundsiebzig), but unlike that of Swedish (fyrtiotvå, tvåhundrasjuttiofem).

Adjectives and adverbs


There are three forms of the adjective in Danish:

  1. basic form or common, used with singular words of the common gender ("n-words").
    en billig bog, "a cheap book"; en stor dreng, "a big boy"
  2. t-form or neuter, used with singular words of the neuter gender ("t-words") and as an adverb.
    et billigt tæppe, "a cheap carpet"; et stort hus, "a big house"
    han bor billigt, "he has a low rent (lit. lives cheaply)"
  3. e-form or plural / definite, used in the plural and with a definite article, a pronoun or a genitive.
    den billige bog, "the cheap book"; hans store hus, "his big house"
    billige bøger, "cheap books"; store huse, "big houses"

Only words ending in a consonant take -e. Only words ending in a consonant or the vowels -i or -å take -t. Others are unchanged.


The adjective must agree with the word that it qualifies in both gender and number. This rules also applies when the adjective is used predicatively: huset er stort, "the house is big", or bøgerne er billige, "the books are cheap".

An exception to the rule of agreement are the superlative and, in regular prose, the past participle when used in the verbal meaning (e.g. børnene er sluppet løs, "the children have been let out", but børnene er løsslupne, "the children are unrestrained").

Definite form

The definite e-form is historically identical to the so-called weak declension of the Germanic adjective, cf. German ein großes Haus, "a big house" ~ das große Haus, "the big house". But whereas the German definite form is not used after a genitive (Peters großes Haus), or following the bare forms of the possessive and indefinite pronouns (mein, kein großes Haus) – but conversely is used after the indefinite pronoun in the forms that have an ending (meinem, keinem großen Haus = dem großen Haus) – the Danish definite form is used in all instances after any determiner save the indefinite article:
Singular Plural

Three degrees of comparison

The Danish adjectives and adverbs are inflected according to the three degrees of comparison. The comparative has the ending -ere (sometimes -re) and the superlative has the ending -st (sometimes -est): e.g. hurtig, hurtigere, hurtigst, "quick, -er, -est"; fræk, frækkere, frækkest, "impertinent/audacious/kinky, -er, -est"; lang, længere, længst (with umlaut), "long, -er, -est". The choice between -st and -est is determined by the syllable structure (to avoid uncomfortable consonant clusters), whereas the variant -re is used only in a few frequent comparatives.

In many cases, especially in longer words and words of a Latin or Greek origin, the comparative and superlative are formed with the adverbs mere and mest instead: e.g. intelligent, mere intelligent, mest intelligent.

The comparative is inflexible, and it is not used with the definite article (in which case Danish uses the superlative instead). The conjunction of comparison is end, "than".

The superlative is inflected like the positive (the t-form being identical to the n-form); længst, længste. When used as a predicate, the basic form is used instead of the e-form: hans ben er længst, "his legs are the longest".


The inflection of some adjectives is irregular:

  • Ny (new) and fri (free) take -t and optionally -e, even though they end in vowels.
  • Several common adjectives with the suffix -s (historically the ending of the genitive) are inflexible, e.g. fælles, "common" (: fælle, "fellow"); ens, "identical" (: en "one"); træls, "annoying" (: træl, "slave") (one also hears trælst, trælse).
  • Adjectives with the very common -sk ending are special. If they are polysyllabic or refer to a country, geographic area or ethnic group, they never take -t. Et klassisk stykke (a classical piece), et svensk hus (a Swedish house). Otherwise the -t is optional. Et friskt pust, or et frisk pust (a breath of fresh air).
  • Some words never take the t-ending: stems ending in another -t (e.g. mat, "weak"; sort, "black") stems ending in -et (-ed) [-əð̪] (e.g. tobenet, "biped"; elsket, "loved"; fremmed, "foreign").
  • The t-form sometimes undergoes phonetical changes that are not reflected orthographically, especially shortening of the preceding vowel or assimilation of a preceding consonant: e.g. god [ɡ̊oːˀ(ð̪)] : godt [ɡ̊ʌd̥]; ny [nyːˀ] : nyt [nyd̥]; syg [syːˀ(j)] : sygt [syɡ̊d̥]. The adjectives ending in -en (originally past participles of the strong verbs) have either -ent [-ənd̥] or -et [-əð̪] in the t-form: e.g. et sunke(n)t skib, "a sunken ship"; et give(n)t antal, "a given number" (the choice is often a matter of style or tradition).
  • Adjectives in -vis have an optional -t in the t-form: et gradvis(t) salg, "a phased sale".
  • Some adverbs may be formed with the basic form instead of the t-form, especially those ending in -ig and -lig -vis: det forstår han selvfølgelig ikke, "of course, he doesn't understand"; The t-less form of such adverbs is obligatory when the adverb is isolated (i.e. with no corresponding adjective) or the meaning of the adverb is essentially different from that of the adjective (e.g. endelig, "finally, at last" ~ endeligt, "definitively"). In other cases, the t-less form is preferred when the adverb qualifies an adjective (e.g. væsentlig(t) større, considerably larger").
  • The comparative and superlative of some frequent adjectives have umlaut: e.g. lang, længere, længst, "long, longer, longest"; ung, yngre, yngst, "young, younger, youngest; stor, større, størst, "big, bigger, biggest.
  • One adjective is suppletive: lille, "little, small" (n- and t-form and definite e-form) ~ små (plural e-form), småt (adverb t-form). Six adjectives are suppletive in the three degrees of comparison: god, bedre, bedst, "good, better, best"; dårlig, værre, værst, "bad, worse, worst"; gammel, ældre, ældst, "old, older, oldest", mange, flere, flest; "many, more, most"; megen/-et, mere, mest, "much, more, most"; lille / lidt, mindre, mindst "little, less / smaller, least / smallest". Irregular, but not suppletive are få, færre, færrest, "few, fewer, fewest" and nær, nærmere, nærmest, "close, closer, closest".
