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 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]
