The voiced uvular fricative or approximant is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʁ⟩, an inverted small uppercase letter ⟨ʀ⟩,[1] or in broad transcription ⟨ɣ⟩ or (if rhotic) ⟨r⟩. This consonant is one of several collectively called guttural R when found in European languages.

↑Based on the approximant ⟨ɹ⟩ and the general tendency to rotate letters in the IPA rather than invert them, ⟨ᴚ⟩ might be expected. However, early in the history of the IPA, that letter had been used for the voiceless fricative, now written ⟨χ⟩, paralleling ⟨ᴙ ʀ⟩ for the voiceless and voiced trills.
