Alveolar approximant

The alveolar approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is ⟨⟩, a lowercase letter r rotated 180 degrees, or in broad transcription ⟨⟩; the equivalent X-SAMPA symbol is ⟨r\⟩.

For ease of typesetting, the vast majority of English phonemic transcriptions use the symbol ⟨⟩ instead of ⟨⟩, even though the former symbol technically represents the alveolar trill.
