Ȳ

latinx|Ȳ (minuscule: latinx|ȳ) is a letter of the Latin alphabet, formed from Y with the addition of a macron (¯).

In modern dictionaries and textbooks for Latin and Old English, unicode|ȳ may be used to indicate a long "y" (IPA: IPA|/yː/). In Latin, this only occurs in loanwords. It is also used in Livonian and Cornish language.
