Questions

Questions people ask about this.

How is "sincerely" stressed in American English?

Stress falls on the second syllable — say "SEER" with a longer, fuller vowel and keep every other syllable short and quick. The respell "sihn-SEER-lee" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.

How do I pronounce the R in "sincerely"?

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 "sincerely" 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 "sihn-SEER-lee" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
