How to pronounce adaptation in American English
a·duhp·TAY·shuhn
Start here
Americans pronounce adaptation as a-duhp-TAY-shuhn (/ˌædəpˈteɪʃən/). In "adaptation", 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, and it's one of the defining features of casual American English. So instead of a·tuhp·TAY·shuhn, you get A·duhp·TAY·shuhn. Stress falls on the third syllable — keep everything else short and quick. You'll hear it in sentences like "He directed a modern adaptation of a Shakespearean tragedy" or "I was disappointed when the movie adaptation changed the ending" — more examples below.

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 "adaptation", 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.
a-tuhp-TAY-shuhn→A·duhp·TAY·shuhn
02
Releasing the final consonant with a puff of air.
In "adaptation", the "t" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
adaptation→A·duhp·TAY·shuhn
03
Inserting a vowel before the syllabic consonant.
In "adaptation", the short unstressed vowel before "n" disappears — the schwa is absorbed and the "n" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
adaptation→A·duhp·TAY·shuhn
04
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch TAY — keep everything else short and quick.

Questions
Questions people ask about this.
How is "adaptation" stressed in American English?
Stress falls on the third syllable — say "TAY" with a longer, fuller vowel and keep every other syllable short and quick. The respell "a-duhp-TAY-shuhn" 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 "adaptation"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "adaptation" sounds closer to "a-duhp-TAY-shuhn" 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 second syllable in "adaptation" 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 "a-duhp-TAY-shuhn" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "adaptation" 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 "a-duhp-TAY-shuhn" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
