Modifitseerivaid

Modifitseerivaid is an Estonian grammatical form, specifically the partitive plural attributive form of the present active participle modifitseeriv, which comes from the verb modifitseerima meaning to modify. The word functions as a participial adjective meaning “modifying” or “that modify” and is used to describe plural nouns in the partitive case.

In practice, modifitseerivaid describes things that perform or involve modification. For example, modifitseerivaid toiminguid means “modifying actions” or “actions that modify,” modifitseerivaid näiteid means “modifying examples,” and modifitseerivaid omadusi means “modifying properties.” The form is used attributively, linking directly to the noun it describes and indicating that the noun is in the partitive plural.
