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).
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.
