-n, -et or -t), depending on its gender and if the noun ends in a vowel or not. The definite articles den, det, and de are used for variations to the definitiveness of a noun. They can double as demonstrative pronouns or demonstrative determiners when used with adverbs such as här ("here") or där ("there") to form den/det här (can also be "denna/detta") ("this"), de här (can also be "dessa") ("these"), den/det där ("that"), and de där ("those"). For example, den där fisken means "that fish" and refers to a specific fish; den fisken is less definite and means "that fish" in a more abstract sense, such as that set of fish; while fisken means "the fish". In certain cases, the definite form indicates possession, e. g., jag måste tvätta håret ("I must wash my hair"). Adjectives are inflected in two declensions – indefinite and definite – and they must match the noun they modify in gender and number. The indefinite neuter and plural forms of an adjective are usually created by adding a suffix (-t or -a) to the common form of the adjective, e. g., en grön stol (a green chair), ett grönt hus (a green house), and gröna stolar ("green chairs"). The definite form of an adjective is identical to the indefinite plural form, e. g., den gröna stolen ("the green chair"), det gröna huset ("the green house"), and de gröna stolarna ("the green chairs"). Swedish pronouns are similar to those of English. Besides the two natural genders han and hon ("he" and "she"), there are also the two grammatical genders den and det, usually termed common and neuter. In recent years, a gender-neutral pronoun hen has been introduced, particularly in literary Swedish. Unlike the nouns, pronouns have an additional object form, derived from the old dative form. Hon, for example, has the following nominative, possessive, and object forms: hon – hennes – henne Swedish also uses third-person possessive reflexive pronouns that refer to the subject in a clause, a trait that is restricted to North Germanic languages: Anna gav Maria sin bok.; "Anna gave Maria her [Anna's] book." (reflexive) Anna gav Maria hennes bok.; "Anna gave Maria her [Maria's] book." (not reflexive) Swedish used to have a genitive that was placed at the end of the head of a noun phrase. In modern Swedish, it has become an enclitic -s, which attaches to the end of
