 Adjectives are inflected in two <unk> — 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 <unk> <unk> ( a green chair ) , ett <unk> hus ( a green house ) , and gröna <unk> ( " 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 <unk> ( " the green chairs " ) .
