Questions
Questions people ask about this.
Is the American pronunciation of "boil" 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 "BOYL" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
