FLEK-shuhn
/ˈflɛkʃən/
Flexion is pronounced FLEK-shuhn (/ˈflɛkʃən/). It has two syllables (Flex-ion), with the stress on "Flex". Flexion is a noun referring to the act of bending a joint or limb, or the state of being bent. In biology and medicine it describes a bending movement, often contrastive to extension. It can also denote the curvature of an organ or tissue, or the process of flexing a muscle during movement.

- You may insert an extra vowel in the second syllable (e.g., /flɛkˈiən/). Resist: maintain /ʃən/ with a short, relaxed schwa. - Over-aspirating the /k/ can distort the word; keep it crisp and brief: /flɛk/ then immediately /ʃən/. - The /ɛ/ in the first syllable should be open-mid; avoid a rounded or tense vowel that makes it sound like /flæks/.
How to Pronounce Flexion
"The doctor noted a painful flexion of the knee after the injury."
"Forearm flexion exercises help improve upper-arm strength."
"The sciatic nerve shows limited flexion due to inflammation."
You pronounce it as /ˈflɛk.ʃən/. The primary stress falls on the first syllable: FLEK-shən. Start with the short “e” as in “bet,” then a crisp “k” followed by “sh” as in “sure” and finish with a weak “ən.” It helps to pair the two-syllable rhythm: stressed syllable then lighter ending. Listen for exact IPA cues: ˈflɛk.ʃən.
Two common errors are treating the second syllable as /ən/ with an extra vowel sound orificando centering of the /ʃ/ becoming /s/. To correct: keep the /ʃ/ as a single palato-alveolar fricative and reduce the final vowel to a reduced schwa /ən/. Don’t overemphasize the /k/; keep it crisp, not aspirated. Practice the sequence: /flɛk/ + /ʃən/ with a gentle glide into the final schwa.
Across US, UK, and AU, the core /ˈflɛk.ʃən/ stays consistent: the first syllable with a short e, the second with /ʃən/. Minor differences: US may have slightly stronger rhotics in connected speech; UK and AU often reduce the final vowel more, giving a subtler /ən/. The /ɛ/ in “fleck” remains an open-mid front vowel in all three, and the /k/ remains a hard stop across contexts.
The difficulty lies in sequencing a crisp /k/ immediately before /ʃ/ and then a reduced final syllable /ən/. The transition from a plosive to a palato-alveolar fricative requires precise tongue placement and timing. Also, the final unstressed syllable reduces to a quick schwa, which can blur in rapid speech. Focus on keeping the /k/ strong but not aspirated, and allow the /ʃən/ to flow as a light, fading ending.
A unique aspect is the clear separation between /flɛk/ and /ʃən/ with a perceptible boundary, reflecting the two-syllable structure. The first syllable carries primary stress, while the second is unstressed and reduced. Pay attention to the transition: the tongue moves quickly from the front-closed position for /ɛ/ to the alveopalatal /ʃ/ without extra vowel in between. This boundary helps listeners identify the term as a clinical noun.

- US: emphasize rhotic linking and a slightly stronger final schwa; /ˈflɛk.ʃən/ with a short, muted /ən/. - UK: pronounced with a crisp /flɛk/ and a lighter /ʃən/, less vowel reduction in rapid speech; still non-rhotic, but the /r/ is not pronounced. - AU: similar to US, but often quicker in casual speech; vowel qualities are fronted slightly more in some speakers, and final /ən/ is commonly reduced to a near-schwa.
Flexion comes from the Latin flexio, from fingere meaning to bend, shape, or fashion. The root flex- means bend. The Latin term flexion entered English via the Middle French flexion and medical Latin, where it was used in anatomy to describe bending joints. The concept evolved in the study of body movement and physiology as scientists distinguished flexion, extension, and other angular changes. First attested in English in the 17th century, flexion has since become a standard term in clinical medicine, orthopedics, anatomy textbooks, and biomechanics, commonly used in phrases like flexion contracture, hip flexion, knee flexion, or spinal flexion. Over time the word widened beyond pure anatomy into general use to describe any act of bending or curving, though in medical contexts it retains precise anatomical meaning. In contemporary usage, flexion is almost always paired with extension to describe the range of motion of joints, with modern imaging and gait analysis frequently referencing flexion angles and degrees as part of assessment and therapy.
