Ɽ, ɽ is a letter of the Latin alphabet, derived from R with the addition of a tail. Its capital form may be based on either the uppercase or lowercase R.
⟨ɽ⟩ is used in the International Phonetic Alphabet to represent a retroflex flap.
The lowercase (ɽ) was added to Unicode since Unicode 1.0 while the uppercase (Ɽ) has only been added since Unicode 5.0.
Ɽ is also used in the alphabets of several Sudanese languages, including Heiban, Koalib, Moro and Otoro. It is placed after R in alphabetical order.
