Use when translating or localizing UI strings, marketing copy, documentation, or any source text into Turkish (Türkçe) for Turkey and Northern Cyprus. Turkic agglutinative, NO gender. The critical trap is dotted vs dotless i — İ/i and I/ı are separate phonemes; capitalization must preserve dot status (istanbul→İstanbul, ışık→IŞIK). Enforces two-dimensional vowel harmony, six-case suffixes, SOV order, siz/sen formality (siz default), singular noun after numbers (5 dosya), apostrophe before suffixes on proper nouns (Türkiye'de), sentence case not Title Case, TDK anti-anglicism (indirmek not downloadlamak), DD.MM.YYYY, and TRY ₺ (1.234,56).
