The voiced uvular approximant is also found interchangeably with the fricative, and may also be transcribed as ⟨ʁ⟩. Because the IPA symbol stands for the uvular fricative, the approximant may be specified by adding the downtack: ⟨ʁ̞⟩, though some writings[1] use a superscript ⟨ʶ⟩, which is not an official IPA practice.
