Ü in the context of "Turkish alphabet"

The Turkish alphabet reform (Turkish: Harf Devrimi or Harf İnkılâbı) is the general term used to refer to the process of adopting and applying a new alphabet in Turkey, which occurred with the enactment of Law No. 1353 on "Acceptance and Application of Turkish Letters" on 1 November 1928. The law was published in the Official Gazette on 3 November 1928, and came into effect on that day. With the approval of this law, the validity of the Ottoman Turkish alphabet, which was based on the Arabic script, came to an end, and the modern Turkish alphabet based on the Latin script was introduced.

The Turkish alphabet differs somewhat from the alphabets used in other languages that use the Latin script. It includes letters modified to represent the sounds of the Turkish language (e.g., Ç, Ö, Ü), including some unused in other languages (Ş, Ğ, contrasting dotted and undotted İ / I). The pronunciation of some letters in the Turkish alphabet also differs from the pronunciation of said letters in most other languages using the Latin alphabet. For example, the pronunciation of the letter C in the Turkish alphabet is /d͡ʒ/, the equivalent of J in English, whereas in the English alphabet, it represents the /k/ or /s/ sound.

U with double acute (Ӳ ӳ; italics: Ӳ ӳ) is a letter of the Cyrillic script, derived from the Cyrillic letter U (У у У у).

U with double acute is only used in the Chuvash language, where it represents the close front rounded vowel /y/, the pronunciation of the Latin letter U with umlaut (Ü ü) in German. It is placed between ⟨У⟩ and ⟨Ф⟩ in the Chuvash alphabet. It is usually romanized as ⟨Ü⟩ but its ISO 9 transliteration is ⟨Ű⟩.

The modern German alphabet consists of the twenty-six letters of the ISO basic Latin alphabet plus four extra letters placed at the end:

German uses letter-diacritic combinations (Ä/ä, Ö/ö, Ü/ü) using the umlaut and one ligature (ẞ/ß (called eszett (sz) or scharfes S, sharp s)), but they do not constitute distinct letters in the alphabet.

Yu or Ju (Ю ю; italics: Ю ю or Ю ю; italics: Ю ю) is a letter of the Cyrillic script used in East Slavic and Bulgarian alphabets.

In English, Yu is commonly romanized as ⟨yu⟩ or ⟨ju⟩. In turn, ⟨ю⟩ is used, where available, in transcriptions of English letter ⟨u⟩ (in open syllables), and also of the ⟨ew⟩ digraph. The sound [y], like ⟨u⟩ in French and ⟨ü⟩ in German, may also be approximated by the letter ⟨ю⟩.

The close front rounded vowel, or high front rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨y⟩. Across many languages, it is most commonly represented orthographically as ⟨ü⟩ (in German, Turkish, Estonian and Hungarian) or ⟨y⟩ (in Danish, Norwegian, Swedish, Finnish and Albanian) but also as ⟨u⟩ (in French and Dutch and the Kernewek Kemmyn standard of Cornish); ⟨iu⟩/⟨yu⟩ (in the romanization of various Asian languages); ⟨уь⟩ (in Cyrillic-based writing systems such as that for Chechen); or ⟨ү⟩ (in Cyrillic-based writing systems such as that for Tatar).

Short /y/ and long /yː/ occurred in pre-Modern Greek. In the Attic and Ionic dialects of Ancient Greek, front [y yː] developed by fronting from back /u uː/ around the 6th to 7th century BC. A little later, the diphthong /yi/ when not before another vowel monophthongized and merged with long /yː/. In Koine Greek, the diphthong /oi/ changed to [yː], likely through the intermediate stages [øi] and [øː]. Through vowel shortening in Koine Greek, long /yː/ merged with short /y/. Later, /y/ unrounded to [i], yielding the pronunciation of Modern Greek. For more information, see the articles on Ancient Greek and Koine Greek phonology.
