Shapes of Latin upsilon as drawn in the African reference alphabet, clearly based on a modern shape of the Greek letter upsilon, but with an uppercase ambiguously similar to an uppercase U with serif.

The letter Ʊ (minuscule: ʊ), called Latin upsilon, is a letter of the Latin alphabet. While its form superficially resembles an upside-down capital Greek letter omega (Ω), it is derived from the Greek lowercase upsilon (υ).[1]

Its lowercase is used in the International Phonetic Alphabet to transcribe a near-close near-back rounded vowel.

It is used in some alphabets of African languages, such as in one of the Kabiyé orthographies.

Use on computers[edit]

The majuscule and the minuscule are located at U+01B1 and U+028A in Unicode, respectively.
