Linking Rs

In non-rhotic accents, where the R's drop after vowels, it's very common for the Rs to come back in when they are at the end of a word and it connects to a word that follows which starts with a vowel sound. This is common for many British accents, and even a number of American ones, in addition to Aussies, New Zealanders, and many others.

In many non-rhotic southern and South African accents don't really have much in the way of "linking R"

... non-rhotic accent adds up an extra difficulty to the already difficult English pronunciation system ... I prefer the rhotic ...

But some people also insert an "r" after "saw". It sounds weird to me as an ESL student
