sedmery, sedmerý

Gramatika: classifying numeral usually used for enumerating nouns that have only the plural forms (e.g. sedmery dveře, 7 doors) and types/classes of things (sedmerý dveře, 7 types of doors; e.g. front, back, bathroom, ...) For the latter usage, adjective-type eding -ý is used as opposed to noun-type ending (-y for masc. and fem. and -a for neuter nouns). As seen here, however, classifier numberals are even used to indicate simple number, often with a folktale-like nuance
