Questions

Questions people ask about this.

How is "plankton" stressed in American English?

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

Why does the second syllable in "plankton" reduce to "uh"?

Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "PLANGK-tuhn" shows the reduced form so you can hear the casual rhythm directly.

Is the American pronunciation of "plankton" 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 "PLANGK-tuhn" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
