How to Pronounce Adrenaline
"The roller coaster gave me a rush of adrenaline."
"Athletes often rely on adrenaline to push through fatigue."
"The news of the rescue spiked her adrenaline and focus."
Pronounce as /əˈdrɛnəlˌiːn/ (uh-DR—nel-een). The primary stress falls on the second syllable: ad-REN- a- line. Start with a schwa, then a short “dren” with a clear E, and end with a long “een.” Tip: keep the final -ine sounding like “een.” Audio cues: you’ll hear the emphasis on the “ren” syllable; try matching the rhythm to “uh-DREN-uh-leen.”
Two common errors: (1) Misplacing stress, pronouncing with even stress like /ˈædɹənəˌlɪn/ or /əˈdrɛn̩əˌlɪn/. (2) Slurring the final -ine into a quick “in” or “een,” producing /ˈædrənəlɪn/ or /ˌædrənˈiːn/. Correction: maintain primary stress on the second syllable; clearly articulate the /l/ before the final /iːn/. Practice with the sequence ad-REN-uh-leen, ensuring the final vowel is a long ee.
In US English, /əˈdrɛnəlˌiːn/ with clear r-like rhotics and a tense final /iːn/. UK English may reduce the first vowel slightly and emphasize /ˈdrɛn/ with less rhoticity, yielding /ˌædˈrenəˌliːn/ depending on speaker. Australian tends to a more clipped /ˌædˈrɛnəˌliːn/ with a brighter vowel in the first syllable and a strong final long /iːn/. Across accents the primary stress remains on the second syllable, but vowel qualities differ ( sprang from rhoticity and nucleus vowel).
Key challenge is the multi-syllabic structure with three vowels in sequence: /əˈdrɛnəlˌiːn/. The middle syllable has a tense /ɛ/ in a connected stream, and the final -ine adds a long /iːn/ sound that may slide to /ɪn/ for some speakers. Additionally, the blend of /dr/ and the light /l/ before the final vowel can trap the tongue. Focusing on clear syllable boundaries and keeping the /n/ before /iːn/ helps stabilize pronunciation.
A distinctive feature is the /dr/ cluster at the start of the stressed syllable and the onset of the syllable containing the /l/ before the final /iːn/. Emphasize the /dr/ with a light, quick release, then glide into the /ɛn/ nucleus before the clear /əl/ transition into /iːn/. The long final /iːn/ often requires a slightly tenser high front vowel with careful lip rounding to avoid a clipped ending and to preserve the long vowel duration.

Adrenaline comes from the Latin adrenal (ad- + ren) meaning “near the kidney,” from ad- ‘near’ and renes ‘kidney’, plus the modern scientific ending -ine. The term was adopted in English in the 19th century as scientists identified adrenaline as a hormone produced by the adrenal glands. The root concept ties to the glands’ location near the kidneys, and the word’s meaning evolved from anatomical reference to its role in physiology and psychology. In the late 1800s and early 1900s, researchers clarified that adrenaline acts as a neurotransmitter and hormone, mediating rapid physiological responses to stress. Over time, the spelling and usage settled predominantly as adrenaline in British English and as epinephrine in American English, with epinephrine often preferred in medical contexts. The word’s journey mirrors advances in endocrinology and pharmacology, as scientists discovered its pharmacological applications in treating anaphylaxis and cardiac conditions, cementing adrenaline’s global recognition both as a natural hormone and a therapeutic agent.
