How to pronounce flexibility in American English
flehk·suh·BIH·luh·tee
Start here
Americans pronounce flexibility as flehk-suh-BIH-luh-tee (/ˌflɛksəˈbɪləɾi/). In "flexibility", 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. It comes out as FLEHK·suh·BIH·luh·tee. Stress falls on the third syllable — keep everything else short and quick. You'll hear it in sentences like "The stretching class focuses on breathing and flexibility" or "I appreciate your flexibility in accommodating our requirements" — more examples below.

l/l/
Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

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 "flexibility", 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.
flehk-suh-BIH-luh-tee→FLEHK·suh·BIH·luh·tee
02
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch BIH — keep everything else short and quick.
FLEHK·SUH·bih·LUH·TEE→FLEHK·suh·BIH·luh·tee
03
Pronouncing the unstressed 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.

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