yapabil
Yapabil is a theoretical lexical stem used in linguistic descriptions of Turkish and related Turkic languages to illustrate the potential or ability construction. It is not a word used independently in standard Turkish; instead, it appears in grammars as the abstract base from which the real verb form yapabilmek ("to be able to do") is derived. The term helps linguists discuss how potentiality is encoded in agglutinative morphology.
Etymology and morphology: Yapabil is built from the verb yap- ("to do") combined with the potential affix
Usage and context: In grammar manuals, yapabil is used to illustrate the boundary between lexical meaning (do)

Note: Yapabil is a construct for pedagogy and theoretical discussion rather than a standalone lexical item
