Questions

Questions people ask about this.

How is "butterfly" stressed in American English?

Stress falls on the first syllable — say "BUH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "BUH-ter-flahy" 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 "butterfly"?

In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "butterfly" sounds closer to "BUH-ter-flahy" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.

How do I pronounce the R in "butterfly"?

Americans use a relaxed retroflex R: the tongue curls back rather than rolling, and the R is one continuous sound with the vowel before it — not two separate sounds. Don't try to pronounce a separate vowel followed by a separate R. Treat them as a single shape.

Is the American pronunciation of "butterfly" 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 "BUH-ter-flahy" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
