IPA phonetic symbol 〚ɹ〛

The IPA phonetic symbol [ɹ] represents an alveolar approximant, like the most common pronunciation of the English phoneme /r/ (as in red).

The symbol /r/ is used instead of /ɹ/ because it is more familiar. However when using a narrow notation it must be noted that [r]  is the initial sound of Roma pronounced in Italian or Spanish.
