Questions
Questions people ask about this.
How is "mutates" stressed in American English?
Stress falls on the first syllable — say "MYOO" with a longer, fuller vowel and keep every other syllable short and quick. The respell "MYOO-tayts" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why doesn't the T sound like a T in "mutates"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "mutates" sounds closer to "MYOO-tayts" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Is the American pronunciation of "mutates" 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 "MYOO-tayts" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
