Sulkeutuvan

Sulkeutuvan is a Finnish linguistic term that denotes the genitive singular form of the present active participle sulkeutuva, derived from the verb sulkeutua, meaning "to close" or "to shut." The present active participle in Finnish functions as an adjective or noun and denotes something that is in the process of closing or that has the property of closing. In grammars, sulkeutuva used attributively agrees with the noun it modifies, including its case.

Usage example: sulkeutuvan oven mekanismi translates to "the mechanism of the closing door." Here sulkeutuvan is the genitive singular form of the participle sulkeutuva. Other inflected forms exist, such as nominative "sulkeutuva" (the closing one) and partitive "sulkeutuvaa." The exact endings depend on case and number.

The term is primarily encountered in linguistic descriptions and grammar references rather than common speech, and may appear in dictionaries, language guides, or academic analyses of Finnish syntax.
