Rhoticity in English
Pronunciation of 'r' across English dialects
The distinction between rhoticity and non-rhoticity is one of the most prominent ways in which varieties of the English language are classified. In rhotic accents, the sound of the historical English rhotic consonant, /r/, is preserved in all phonetic environments. In non-rhotic accents, speakers no longer pronounce /r/ in postvocalic environments: when it is immediately after a vowel and not followed by another vowel.
