How to pronounce capacity in American English
kuh·PA·suh·tee
Start here
Americans pronounce capacity as kuh-PA-suh-tee (/kəˈpæsəɾi/). In "capacity", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, a small move that separates 'classroom' from 'native'. It comes out as kuh·PA·suh·tee. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "The system is operating at maximum capacity".

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Saying a hard "T" in the middle.
In "capacity", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
kuh-PA-suh-tee→kuh·PA·suh·tee
02
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch PA — keep everything else short and quick.
KUH·pa·SUH·TEE→kuh·PA·suh·tee
03
Pronouncing the first syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
KUH·PA·suh·tee→kuh·PA·suh·tee
Questions
Questions people ask about this.
How is "capacity" stressed in American English?
Stress falls on the second syllable — say "PA" with a longer, fuller vowel and keep every other syllable short and quick. The respell "kuh-PA-suh-tee" 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 "capacity"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "capacity" sounds closer to "kuh-PA-suh-tee" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Why does the first syllable in "capacity" 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 "kuh-PA-suh-tee" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "capacity" 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 "kuh-PA-suh-tee" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
