How to pronounce adrenaline in American English
uh·DREH·nuh·leen
Start here
Americans pronounce adrenaline as uh-DREH-nuh-leen (/əˈdrɛnəlin/). In "adrenaline", the "dr" cluster blends into a "jr" sound — a natural American English pronunciation. This is called the DR Sounds Like JR, a small move that separates 'classroom' from 'native'. It comes out as uh·DREH·nuh·leen. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "He felt a rush of adrenaline before stepping onto the stage".

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Saying a clean "dr" instead of a "j" sound.
In "adrenaline", the "dr" cluster blends into a "jr" sound — a natural American English pronunciation. /d/ shifts toward /dʒ/ ("j"), so DR sounds like "jr".
uh-DREH-nuh-leen→uh·DREH·nuh·leen
02
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch DREH — keep everything else short and quick.
UH·dreh·NUH·LEEN→uh·DREH·nuh·leen
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.
UH·DREH·nuh·leen→uh·DREH·nuh·leen
Questions
Questions people ask about this.
How is "adrenaline" stressed in American English?
Stress falls on the second syllable — say "DREH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "uh-DREH-nuh-leen" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the first syllable in "adrenaline" 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 "uh-DREH-nuh-leen" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "adrenaline" 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 "uh-DREH-nuh-leen" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
