The letterƱ (minuscule:ʊ), calledhorseshoe or sometimesbucket,inverted omega orLatin upsilon, is a letter of theInternational Phonetic Alphabet used to transcribe anear-close near-back rounded vowel. Graphically, the lower case is a turned small-capital Greek letteromega (Ω) in many typefaces (e.g.Arial,Calibri,Candara,Liberation,Lucida,Noto,Times New Roman), and historically it derives from a small-capital Latin U (ᴜ), with the serifs exaggerated to make them more visible.[1] However,Geoffrey Pullum interpreted it as an IPA variant of the Greek letterupsilon (υ) and called itLatin upsilon, the name that would be adopted by Unicode, though in IPA a letter closer to an actual Greek upsilon is also used for thevoiced labiodental approximant; Pullum called this letterscript V[2] and Unicode calls itV with hook.
Horseshoe is used in theAfrican reference alphabet, and national alphabets such as those ofAnii[3] andTem. It most often has the value of/u/ withretracted tongue root.
The majuscule and the minuscule are located at U+01B1[4] and U+028A[5] inUnicode, respectively.
Derived characters areU+1DB7 ᶷMODIFIER LETTER SMALL UPSILON andU+1D7F ᵿLATIN SMALL LETTER UPSILON WITH STROKE.[6]
