Pronunciation

Isn't is often pronounced in the South Midland and Southern U.S., with , a stop consonant, substituting for , a sibilant. This substitution results from an assimilatory process in which the tip of the tongue, in anticipation of the articulatory position for the following , touches the upper alveolar ridge. This same process gives for wasn't and for business. These pronunciations are heard from speakers on all social levels.

Usage

See contraction.
