Questions

Questions people ask about this.

Is the American pronunciation of "vast" different from British English?

American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "VAST" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
