köpüklerin

Köpüklerin is a Turkish noun form derived from köpük, meaning foam, froth, or lather. It is the genitive plural form of köpük, used to indicate possession or a relationship between foams and another noun (the foams’…).

Morphology and function: Turkish forms compound suffixes in a sequence. From köpük come the plural köpükler (the foams). Adding the genitive suffix -in to the plural yields köpüklerin, which means “of the foams” or “the foams’.” This form is commonly used before a head noun in noun phrases, for example: Köpüklerin yüzeyi (the surface of the foams) or Köpüklerin rengi (the color of the foams). The same pattern applies to other Turkish plural nouns when a genitive relation is expressed.

Usage notes: In Turkish, the genitive is expressed with suffix harmony rather than a separate case ending. Köpüklerin appears in contexts discussing characteristics, ownership, or relationships related to foams, emulsions, or frothy substances. It is not a standalone concept but a grammatical form used within noun phrases.

Etymology and related forms: The base noun is köpük (foam). The plural is köpükler, and the genitive plural is köpüklerin. Related forms include köpük (singular) and köpükler (plural). For broader reference, see also köpük (foam), köpükler (foams), and Turkish genitive suffix -in.
