How to Pronounce Convulsion
"The patient suffered a convulsion during the afternoon nap and was immediately attended to by medical staff."
"A high fever can trigger a convulsion in young children, though most episodes are brief and non-recurrent."
"Scientists studied the patient’s convulsions to assess neurological function after a traumatic brain injury."
Pronounce it as kon-VUL-shun, with the primary stress on the second syllable. IPA: US /kənˈvəlˌʃən/ or /kənˈvɔlʃən/; UK /kənˈvʌl.ʃən/; AU /kənˈvɔlʃən/. Begin with a quick, neutral schwa in the first syllable, then stressed /ˈvəl/ or /ˈvɔl/ followed by /ʃən/. Mouth positions: lips relaxed, tongue in a mid position for the first syllable, then a rounded, high-front movement for /ˈvəl/ or /ˈvɔl/, then a clear /ʃ/ with the blade of the tongue close to the hard palate, and finally /ən/ with a light, unstressed schwa.
Two frequent errors: 1) Misplacing the stress, saying con-VE-lution or con-VOOL-shun. 2) Slurring the /v/ and /l/ into one sound or mispronouncing the /ʃ/ as /s/ or /tʃ/. Correction: keep the root “vul” as a distinct syllable with a clear /v/ followed by /əl/ and then /ʃən/. Practice by isolating the middle syllable: /ˈvəl/ or /ˈvɔl/ before adding the /ʃən/ tail. Use slow repetition: kon-VUL-shun, then faster, ensuring the /ʃ/ is a separate palatal sound rather than an affricate.
US tends to reduce the first syllable to a weak schwa and emphasize the second syllable: /kənˈvəlˌʃən/. UK often features a slightly tighter /ɒ/ in the second syllable and clear /ʃən/, with a non-rhotic accent so r-col is silent. AU mirrors US but may have broader vowel quality in /ɒ/ or /ɔː/ depending on speaker; the /ɪ/ in the final syllable is very light in rapid speech. Across all, the stress remains on the second syllable, with the final /ən/ often unstressed.
The difficulty lies in the consonant cluster /vəlʃ/ where the /v/ transitions rapidly into /l/ and /ʃ/ without vowel intrusion, plus the final /ən/ often reduced. The middle syllable /ˈvəl/ requires a precise vowel quality and a quick, clean /l/ before /ʃ/. Additionally, the word has a non-obvious etymology that places the /v/ and /ʃ/ close together, tempting listeners to misplace the emphasis or blend sounds. Focus on isolating /ˈvəl/ before adding /ʃən/ to stabilize pronunciation.
Convulsion contains no silent letters in the main syllables, but the final /n/ can be lightly unreleased in rapid speech. The letter combination “tion” is heard as /ʃən/, not as separate /t/ + /i/ + /ən/. The tricky part is ensuring the /v/ and /l/ aren’t merged and that /ʃ/ is voiced distinctly. Practicing the /-ʃən/ tail helps: practice /ʃən/ as a unit after the /l/ to avoid inserting a separate vowel.

Convulsion originates from Middle French convulsion, from Latin convulsio, from verb convellere meaning to pull violently apart. The root con- (together) + vellere (to pull) reflects the sense of a body being violently jerked. The word entered English via Latin in the 15th–16th centuries, initially in medical writings to describe violent, involuntary muscle movements. Over time, the term broadened slightly to describe any sudden, convulsive movement disorder, though it remains most at home in medical contexts. Its usage has remained fairly stable, with the modern sense focused on abrupt, involuntary muscle contractions arising from neurological disturbance. First known uses surface in early medical texts of late medieval to early modern Europe, aligning with the period when systematic clinical descriptions of seizures and convulsions began to emerge. Across centuries, the word retained its clinical nuance, contrasting with more mundane spasms or twitches and emphasizing the abrupt, often severe nature of these motor events.
