Linking and intrusive R

Linking R and intrusive R are phonological phenomena that occur in many non-rhotic dialects of English. In all non-rhotic dialects, the phoneme does not appear in the coda of a syllable (so spar is pronounced the same as spa); in dialects with linking and/or intrusive R, however,  may appear at a word boundary before a vowel-initial word.

Linking R
The linking R occurs in most (but not all) non-rhotic dialects of English. In dialects that possess linking R, if a word that ends with precedes a word that begins with a vowel,  will be realized at the onset of the next word. Thus, for example, the R in here would not be pronounced in here they are (because it is followed by a consonant), but it would be pronounced in here I am. Likewise, the R at the end of far would only be pronounced if the next word begins with a vowel, as in far away or far off. In other words, in a non-rhotic dialect with linking R, is retained only if it is followed by a vowel, including across word boundaries.

Intrusive R
Some (but not all) dialects that possess linking R also possess intrusive R. In a dialect with intrusive R, an epenthetic is added after a word that ends in a non-high vowel or glide if the next word begins with a vowel, regardless of whether the first word historically ended with  or not. For example, intrusive R would appear in Asia' and Africa or the idea' of it: Asia and idea did not historically end in, but the is inserted epenthetically to prevent a hiatus. Intrusive R also occurs within words before certain suffixes, such as draw'ing or withdraw'al. This is now so common in England that by 1997 the linguist John C. Wells considered it objectively part of Received Pronunciation, but he noted that it was still stigmatized as an incorrect pronunciation, as it is or was in some other standardized non-rhotic accents.
