If you're a (native) speaker of a non-rhotic dialect of English I wonder whether you ever feel the need to add that [r] either to avoid confusion in the first place or as a means to rectify ambiguity after the fact (especially if your interlocutor has asked you to (and particularly if they are a speaker of a rhotic dialect of English)). For example: - According to local lore, they lived only on raw fish. - What kind of law was that? This, of course, may not be the most natural-sounding example, but still. Thanks.
