Why it sounds different

Why "triathlon" sounds like trahy·ATH·lahn.

Questions

Questions people ask about this.

How is "triathlon" stressed in American English?

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

Is the American pronunciation of "triathlon" 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 "trahy-ATH-lahn" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
