iyi

İyi is a core word in Turkish that serves as an adjective meaning "good" and as an adverb meaning "well." It is used to describe the quality of people, objects, or situations and appears in common phrases such as "İyi bir haber" (good news), "İyi hissetmek" (to feel well), and greetings like "İyi günler" (good day) or "İyi akşamlar" (good evening). The word can also modify other adjectives and nouns (for example, "iyi bir fikir" — a good idea).

Grammatically, iyi forms the basis for comparative and superlative constructions: "daha iyi" (better) and "en iyi" (best). It is a native Turkish term with cognates in related Turkic languages, and its meaning remains stable across contexts, though tone can shift with intonation and formality.

İYİ Parti, commonly rendered as "İYİ" in Turkish or "IYI" in some English-language contexts, is a Turkish political party founded in 2017 by Meral Akşener. The party's name translates to "Good Party" and it positions itself as a centrist, reformist force advocating the rule of law, national unity, and a market-oriented economy. It has held seats in the Turkish parliament and has influenced political discourse as a challenger to the long-dominant parties.
