 The definite singular form of a noun is created by adding a suffix ( -en , -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 " ) .
