Danish grammar is either the study of the grammar of the Danish language, or the grammatical system itself of the Danish language. Danish is often described as having ten word classes: verbs, nouns, pronouns, numerals, adjectives, adverbs, articles, prepositions, conjunctions, and interjections. The grammar is mostly suffixing. This article focuses on Standard Danish. Nouns Inflections 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) is en for common-gender nouns and et for neuter nouns. They are often informally called n-words and t-words. En dreng. A boy. Et fængsel. A jail. Unlike English, definite nouns in Danish are rendered by adding a suffix (i.e. not an article) to the indefinite form (unless qualified by an adjective; see below). The definite singular ending is -en for common-gender nouns and -et for neuter nouns. Drengen. The boy. Fængslet. The jail. The plural noun suffixes are more complex. The following table shows the possible inflections of regular Danish nouns of both grammatical genders. The most common plural ending is -er. Besides an extremely large number of other nouns, nearly all those that end with unstressed -e take it, as does the vast majority of those that end with a monophthong other than -e. The zero plural ending is predominantly used with neuter nouns. The plural ending -e is used with: a large number of monosyllabic nouns that end with a consonant or diphthong (and any compound ending with one of those monosyllabic nouns) almost all nouns that end with unstressed -er eight common-gender nouns that end with unstressed -el: apostel, discipel, djævel, engel, himmel, stimmel, vrimmel, variabel some of the nouns denoting persons that end with -ing (all of which are common gender) some other common-gender plurisyllabic nouns In the singular definite, common-gender nouns always take the ending -en, while neuter nouns always take -et. Plural definite adds -ene to the indefinite if it has no suffix or a borrowed suffix, otherwise -ne (exception: mennesker "human beings, people" → menneske(r)ne). Nouns that end in unstressed -e lose the -e when adding an ending: kvinde, kvind-en, kvind-er, kvind-erne "woman". Nouns that end in unstressed -er, -el, or -en lose or keep the e according to the rules below. When the loss of the e leads to a double consonant coming immediately before the stem-final r, l, or
