Close front rounded vowel
|Close front rounded vowel|
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⟩, and the equivalent X-SAMPA symbol is y. Across many languages, it is most commonly represented orthographically as ⟨ü⟩ (in German and Turkish) or ⟨y⟩, but also as ⟨u⟩ (in French and a few other Romance languages); ⟨iu⟩/⟨yu⟩ (in the romanization of various Asian languages); ⟨ű⟩ (in Hungarian for the long duration version; the short version is the ⟨ü⟩ found in other European alphabets); ⟨уь⟩ (in Cyrillic-based writing systems such as that for Chechen); or ⟨ㅟ⟩ (in Hangul, used for Korean).
The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists, perhaps a majority, prefer the terms "high" and "low", and these are the only terms found in introductory textbooks on phonetics such as those by Peter Ladefoged.
In most languages, this rounded vowel is pronounced with compressed lips ('exolabial'). However, in a few cases the lips are protruded ('endolabial').

- Its vowel height is close, also known as high, which means the tongue is positioned as close as possible to the roof of the mouth without creating a constriction that would be classified as a consonant.
- Its vowel backness is front, which means the tongue is positioned as far forward as possible in the mouth without creating a constriction that would be classified as a consonant.
- Its roundedness is compressed, which means that the margins of the lips are tense and drawn together in such a way that the inner surfaces are not exposed.
Note: Since front rounded vowels are assumed to have compression, and few descriptions cover the distinction, some of the following may actually have protrusion.

Catford notes that most languages with rounded front and back vowels use distinct types of labialization, protruded back vowels and compressed front vowels. However, a few languages, such as Scandinavian ones, have protruded front vowels. One of these, Swedish, even contrasts the two types of rounding in front vowels (see near-close near-front rounded vowel, with Swedish examples of both types of rounding).
As there are no diacritics in the IPA to distinguish protruded and compressed rounding, an old diacritic for labialization, ⟨ ̫⟩, will be used here as an ad hoc symbol for protruded front vowels. Another possible transcription is ⟨yʷ⟩ or ⟨iʷ⟩ (a close front vowel modified by endolabialization), but this could be misread as a diphthong.
- Its vowel height is near-close, also known as near-high, which means the tongue is not quite so constricted as a close vowel (high vowel).
- Its vowel backness is near-front, which means the tongue is positioned almost as far forward as a front vowel.
- Its roundedness is protruded, which means that the corners of the lips are drawn together, and the inner surfaces exposed.
