Sound sample (help·info)

The near-close near-back vowel is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet for the near-close near-back rounded vowel is ‹ʊ›. This derives from a small turned capital Ω; although officially called a small Latin letter upsilon, it bears little resemblance to the Greek upsilon and is informally called "horseshoe u" instead. The equivalent X-SAMPA symbol is U. Prior to 1989, there was an alternate IPA symbol for this sound, ‹ɷ›, called "closed omega". Use of this symbol is no longer sanctioned by the IPA.

Some languages may have a near-close near-back unrounded vowel; since no language is known to contrast rounding of this vowel, the IPA has not devised a standard way to represent this and thus can be represented in a number of ways, including ‹ɯ̽› and ‹ʊ̜›.

There is also a near-close central rounded vowel in some languages.

Features

Its vowel height is near-close, which means the tongue is positioned similarly to a close vowel, but slightly less constricted.
Its vowel backness is near-back, which means the tongue is positioned as in a back vowel, but slightly further forward in the mouth.
Its vowel roundedness is generally rounded, which means that the lips are rounded to a greater or lesser degree, but is sometimes rather ambiguous. Because no language is known to contrast rounding this place of articulation, the IPA has not created separate symbols to show this.
