Turkish alphabet The Turkish alphabet is the modern orthography used for the Turkish language, adopted in 1928 as part of sweeping reforms led by Mustafa Kemal Atatürk and implemented by the Grand National Assembly of Turkey and the Turkish Language Association. It replaced earlier scripts used in Anatolia and the Ottoman domains, influencing literacy, publishing, and national identity across the Republic of Turkey, Turkish Republic of Northern Cyprus, and Turkish-speaking communities in Balkans, Caucasus, and Diaspora of Turkey. The alphabet modified the Latin alphabet to represent phonemes of Turkish more precisely, shaping education, administration, and printing.
The shift to the current alphabet was enacted by law following the Turkish Language Association initiatives and the Alphabet Reform of 1928 promoted during Atatürk's Reforms. Preceding systems included the Arabic script used under the Ottoman Empire and historical writing systems such as the Old Turkic script attested in the Orkhon inscriptions and later adaptations like the Perso-Arabic script employed in Ottoman chancery. Early 20th‑century intellectuals and reformers—among them İsmail Hakkı Tonguç allies in education reform and advocates associated with the Committee of Union and Progress—debated Latinization, influenced by comparative reforms in Azerbaijan and the Soviet Union where some Turkic languages adopted modified Latin alphabets during the 1920s. The law promulgated by the Grand National Assembly of Turkey mandated rapid implementation, accompanied by nationwide literacy campaigns coordinated with institutions like the Ministry of National Education and the People's Houses (Halkevleri). International observers including scholars from League of Nations era linguistics noted the sociopolitical impact of the change.
The alphabet comprises 29 letters derived from the Latin alphabet with modifications to represent Turkish phonology: A, B, C, Ç, D, E, F, G, Ğ, H, I, İ, J, K, L, M, N, O, Ö, P, R, S, Ş, T, U, Ü, V, Y, Z. Phonetic values align with descriptions in phonology studies such as those found in works by linguists associated with Turkish Language Association and comparative analyses in International Phonetic Association resources. Consonantal correspondences relate to sounds familiar from other languages documented by researchers connected to institutions like University of Oxford, Harvard University, and University of Cambridge; for example, C represents /dʒ/ as in parallels to Italian and English borrowings recorded in corpora compiled by the Turkish Historical Society. Vowel harmony, central to Turkish morphophonology and treated in journals published by Boğaziçi University and Istanbul University, governs vowel alternations across suffixes, with front/back and rounded/unrounded distinctions reflected by letters such as Ö and Ü.
Diacritic marks in the alphabet include the cedilla in Ç and Ş, the dot-above distinction between İ and I, and the breve-like modification for Ğ (yumuşak g). These modifications trace typographic conventions used in European orthographies such as French alphabet and German alphabet for similar diacritics, while the dotless I and dotted İ reflect Turkish-specific needs studied in works at Middle East Technical University and typographic design by firms linked to printing houses in Istanbul. Ğ (yumuşak g) functions not as a typical consonant but as a lengthening or glide marker, a phenomenon analyzed in phonetics papers presented at conferences of the Association for Computational Linguistics and the International Congress of Linguists.
Orthographic rules were codified by commissions including members appointed by the Grand National Assembly of Turkey and later standardized by the Turkish Language Association; they govern syllable structure, hyphenation, and the representation of loanwords from Arabic script-based Ottoman vocabulary, Persian language, French language, English language, and regional borrowings from Greek language and Armenian language. Spelling conventions reflect morphemic analyses used in curricula at the Ministry of National Education and lexicographical practices found in dictionaries published by the Turkish Language Association and university presses like İstanbul Üniversitesi Basımevi. Rules for capitalization, punctuation, and transliteration into ISO 9-style transliteration standards intersect with guidelines used in archives such as the Presidency of the Republic of Turkey and repositories like the BIAA and national libraries.
The adoption established a deliberate continuity with the Latin alphabet family while breaking from the Ottoman Turkish orthographic tradition based on the Arabic script adapted for Ottoman phonology. Transitional materials, comparative grammars, and bilingual primers created by commissions drew on models from Azerbaijan Soviet Socialist Republic Latinizations and reforms in Finland and Hungary to justify phoneme-to-letter correspondences. The reform also affected legal instruments, with conversions of laws and administrative registers originally drafted under Ottoman Empire institutions into the new orthography via state archives and initiatives of the Directorate of State Archives.
Instruction in the alphabet was rapidly deployed through mass education campaigns, literacy courses organized by People's Houses, and textbook publication overseen by the Ministry of National Education and printing firms in Ankara and Istanbul. Teacher training programs at institutions such as Gazi University and Ankara University integrated alphabet pedagogy; adult education efforts referenced models from UNESCO and collaboration with foreign linguists from University of Paris and Berlin University. Contemporary usage spans media outlets like TRT and newspapers headquartered in Istanbul, as well as digital platforms operated by companies such as Turkcell and Türk Telekom serving Turkish-script content.
Computational representation relies on standards like Unicode and ISO/IEC 8859-9 (Latin-5) for legacy systems; fonts and keyboard layouts support special characters via implementations in operating systems by Microsoft (Windows), Apple Inc. (macOS), and distributions of Linux with I18N support. Input methods and locale settings conform to standards developed by bodies such as IETF (language tags) and are used in software from companies including Google and Oracle. Scholarly work on Turkish text processing appears in proceedings of the ACL and repositories from research groups at Bilkent University and Sabancı University focusing on tokenization, morphological analysis, and encoding of diacritics.
