:Rhotic:

Pronunciation GB: ˈrəʊtɪk, GA: ˈroʊt̬ɪk

The name applied to those accents of English where the /r/ phoneme may appear before a pause and before a consonant as well as before a vowel. Many American accents are rhotic, as are Scottish, Irish and Western English accents. However, it is clear that the occurrence of /r/ is more complicated than a two-way classification of accents into rhotic and non-rhotic varieties would suggest. Even an accent like General British English (RP), which is supposedly non-rhotic, allows pre-consonantal /r/ on occasion. One example is the word ferrule ˈferjuːl. One solution to this is to label accents as being of high, medium, or low rhoticity.
