isimfiildir

isimfiildir is not a standard or widely used term in major linguistic references. It appears to be either a misspelling or a concatenation of Turkish elements isim (name or noun) and fiil (verb) with the copular suffix -dir, and is not established as a separate category in official Turkish grammar. In practice, the more common term is isim fiil, sometimes referred to as a verbal noun.

In Turkish grammar, an isim fiili (verbal noun) denotes a word form derived from a verb that functions as a noun within a sentence. Verbal nouns cover infinitives and other deverbal nouns that can serve as subject, object, or complement. Examples include sentences such as “Koşmak sağlıklıdır” (Running is healthy) and “Koşmayı seviyorum” (I like running). Such forms may take case markers, and can interact with possessive or object markers when embedded in larger noun phrases.

Usage and scope: The concept helps describe how certain verb-derived forms behave like nouns, as opposed to the verb’s pure, finite use. In teaching and descriptive grammar, the focus is often on how these forms function within clauses and how they contrast with other noun derivations.

Note that if encountered as “isimfiildir,” the most prudent interpretation is that it refers to the Turkish concept of a verbal noun (isim fiil) or is a typographical variant of that term rather than a standalone, widely recognized linguistic category.
