Questions
Questions people ask about this.
How is "highly" stressed in American English?
Stress falls on the first syllable — say "HAHY" with a longer, fuller vowel and keep every other syllable short and quick. The respell "HAHY-lee" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Is the American pronunciation of "highly" 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 "HAHY-lee" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
