Usage notes 
In the phonetic sense, excresence means “insertion of a consonant”, and is synonymous with linking consonant. By contrast, intervocalic means “between vowels”, and is not identical, though in some cases these may coincide. While a consonant may be inserted between vowels (and be an example of both of these), as in synchronic analysis of “an apple” (from a + apple), a consonant may also be inserted between consonants, as is pronuncing warmth as [ˈwɔrmpθ] (adding a [p] between [m] and [θ]).
