Difference among "yeter," "yeterli," and "yeterince."
Could someone please explain the difference among these three? What parts of speech can they be (adverb/adjective/...)? Can they be used interchangeably?
Yeter is a verb. Aorist form of Yetmek, to suffice or to be enough. So, it suffices / it is enough. The negative form is yetmez.
Yeterli is an adjective. Sufficient. The negative form is yeterli değil, it isn't sufficient, or yetersiz, insufficient.
Yeterince is an adverb or an adjective. If it is an adverb, it is "sufficiently" ; if it's an adjective, it's "enough". (ex: yeterince insan öldü. Enough people have died.)
