4 syllables: lo, co, mo, tion. Stress on mo.
loh-kuh-MOH-shuhn
/ˌloʊkəˈmoʊʃən/
locomotion is pronounced loh-kuh-MOH-shuhn (/ˌloʊkəˈmoʊʃən/). It has four syllables (lo-co-mo-tion), with the stress on "mo". Locomotion refers to the action or ability of moving from one place to another, typically using one’s limbs. It encompasses the mechanism and manner of movement in living beings, including walking, running, and other modes of travel. The term is often used in biology, robotics, and physiology to describe movement patterns and their underlying motor control.

"The study compared the locomotion patterns of rats and mice under different treadmill speeds."
"Humans rely on efficient locomotion to navigate urban environments with minimal energy expenditure."
"A new robot prototype demonstrated smooth locomotion over uneven terrain."
locomotion is pronounced as /ˌloʊ.kəˈmoʊ.ʃən/ in US, /ˌləʊ.kəˈməʊ.ʃən/ in UK, and roughly /ˌlɒ.kəˈməʊ.ʃən/ in some Australian guidance. The stress pattern is secondary on the second syllable and primary on the third: lo-CO-mo-tion. Start with a clear “loh” vowel, reduce the second vowel to a schwa, and accent the third syllable with a long “mo” followed by a light “tion.” You’ll want to make the “motion” part crisp: /ˈmoʊ.ʃən/.”,
Common errors include misplacing the stress (giving too much emphasis to the first or second syllable), over-articulating the first vowel, or sliding the /t/ into /ʃ/ into /ən/ sounds. Correct approach: keep a light, unstressed second syllable with a clear /ˈmoʊ/ in the third syllable and a crisp /ʃən/ at the end. Practice with slow, deliberate syllables: lo- co- mo- tion, then speed up while maintaining the same rhythm and vowel lengths.
In US English, you’ll hear /ˌloʊ.kəˈmoʊ.ʃən/ with a rhotic r-neutral schwa before /kə/ and a strong /oʊ/ in the stressed syllable. UK English tends to a non-rhotic /ˌləʊ.kəˈməʊ.ʃən/ with a less pronounced /r/-like quality and a longer, pure /əʊ/ in the second syllable. Australian English often sits between: /ˌlɒ.kəˈməʊ.ʃən/ or /ˌləʊ.kəˈməʊ.ʃən/ with dynamic vowel shifts and a softer final /ən/. The main differences are rhoticity and vowel quality in the first and final stressed vowels.
The difficulty lies in maintaining the multi-syllabic rhythm with accurate stress placement: the primary stress falls on the third syllable, creating a longer /moʊ/ followed by a light /ʃən/. Also, the sequence lo- co- mo- tion requires precise vowel reduction in the second syllable and a clean /ʃ/ before the final schwa, which can be tricky for speakers with different native phoneme inventories.
Locomotion has no silent letters; each letter participates in speech: l-o-c-o-m-o-t-i-o-n. The challenge is not silence but the vowels and the cluster transition: you’ll want a clear /l/ at the start, a soft /k/ after the first vowel, and a crisp /ʃ/ sound before the final /ən/. Focus on keeping the unstressed syllables light while the primary stress lands on the third syllable.

Locomotion comes from the Latin loco, meaning place, and motio, meaning movement. The root loco appears in words like locomote, locomotive, and locality, all sharing the sense of movement from a place. The term entered English in scientific and anatomical discourse in the 19th century, aligning with rapid developments in physiology, biomechanics, and robotics. Early usage often described animal or human movement as a physical process deserving mechanical analysis. Over time, locomotion broadened to include any mode of transport or locomotor activity, extending into engineered systems such as robotic locomotion. The word’s morphology—loc(o) + motion—reflects a compound formed to emphasize how living agents move through space, rather than merely the presence of motion in general. First known uses appear in scholarly medical and zoological texts of the 1800s, where researchers analyzed gait, muscle function, and limb coordination to explain how organisms traverse their environments.
