2 syllables: Mo, tile. Stress on Mo.
MOH-tuhl
/ˈmoʊtəl/
Motile is pronounced MOH-tuhl (/ˈmoʊtəl/). It has two syllables (Mo-tile), with the stress on "Mo". Motile is a term used mainly in biology to describe an organism or cell capable of movement. It designates entities that can actively move themselves, rather than being stationary. In everyday scholarly contexts, motile contrasts with sessile, highlighting an organism’s intrinsic mobility.

"The fertilized egg gives rise to motile sperm that navigate toward the egg."
"Certain bacteria are motile due to flagellar propulsion."
"Motile cells are essential for tissue repair and immune responses."
Say MO-tile, with the primary stress on the first syllable. The IPA for US is /ˈmoʊ.taɪl/, UK /ˈməʊ.taɪl/, and AU /ˈməʊ.taɪl/. Start with a long 'o' as in 'go,' then a clear 'tile' with /taɪ/ as in 'tie.' Keep the second syllable quick and lighter than the first. You can listen to examples on Pronounce or Forvo to hear natural token pronunciation.
Two frequent errors are misplacing the stress and misproducing the /oʊ/ as a short /o/ and confusing /aɪ/ with /iː/. Correct by ensuring the first syllable carries main stress and features a genuine /oʊ/ diphthong, then clearly articulate /taɪl/ with a crisp /t/ and the /aɪ/ glide. Listening to native biology narrations helps internalize the rhythm and vowel length.
In US English, /ˈmoʊ.taɪl/ has a pronounced /oʊ/ and a lightly released final /l/. UK/GA tends toward /ˈməʊ.taɪl/ with a slightly longer /əʊ/ in the first syllable and a non-rhotic /r/ difference not present here. Australian tends to a centralized /ə/ in unstressed syllables and a clear /taɪl/ cluster. Overall, the main differences are vowel quality in the first syllable and the exact vowel duration.
The challenge lies in the diphthong in the first syllable (/oʊ/ or /əʊ/) combined with the swift /taɪl/ transition. Many speakers shorten the /oʊ/ too much or merge /taɪl/ with a near /təl/ ending. Focus on a distinct /oʊ/ or /əʊ/ followed by a crisp /taɪl/, with clear tongue elevation for the high front of the /aɪ/ glide.
The word ends in a clear /l/ with a light, l-vocalized finish in many accents; the consonant is not strongly aspirated. The most distinctive feature is the strong diphthong in the first syllable contrasting with the long, high-front /aɪ/ in the second part. Maintaining a clean separation between /moʊ/ and /taɪl/ helps avoid slurring.

- US: emphasize the rhotic-like syllable; keep /oʊ/ as a tight, rounded diphthong, and end with a precise /l/. - UK: use /əʊ/ for the first vowel; the second syllable retains /taɪl/ with a slightly shorter /əʊ/ length, and an unpronounced postvocalic r (non-rhoticity is standard, though /l/ remains clear). - AU: more centralized first vowel in certain contexts; keep the /taɪl/ portion crisp; the /l/ often has a lighter touch. Reference IPA: /ˈmoʊˌtaɪl/ US, /ˈməʊ.taɪl/ UK/AU.
Motile comes from the Latin motilis, from movere meaning to move. The prefix mo- (from Latin movēre) signals movement, while the suffix -til-e relates to capability. In biological usage, motile describes cells or organisms that can move on their own, as opposed to non-motile or sessile forms. The term appears in scientific literature from the 19th century onward, increasingly common in cellular biology, microbiology, and physiology to distinguish active locomotion capabilities from passive or fixed states. The word’s evolution parallels advances in microscopy and cell biology, where the identification of motility mechanisms such as flagella, cilia, pseudopodia, and contractile proteins refined our understanding of how cells and organisms navigate their environment. The first known uses align with general Latin-rooted scientific language, becoming standardized in English-language biology texts by the late 1800s and early 1900s as a formal descriptor of movement capability in organisms and cells.
