How to Pronounce Costume
"She wore a pirate costume to the party and won the best-dressed prize."
"The theater group rented costumes for the annual performance."
"For Halloween, the kids picked costumes from the attic and painted their faces."
Pronounce as COO-stoom or KAH-stoom with primary stress on the first syllable. IPA US: /ˈkɒs.tjuːm/ (British: /ˈkɒs.tjuːm/), Australian: /ˈkɒs.tjuːm/. The first syllable carries stress; the vowel is a short o, followed by an unstressed /t/ and a /juː/ glide before the final /m/. Try saying: COST-youm, ensuring the ‘st’ cluster and the /t/ are crisp, and finish with a clean /m/.
Common errors include misplacing stress (saying co-STUME) and mispronouncing the middle vowel as /u/ or /ju/ without the correct fronted /t/ transition. Another mistake is softening the /t/ into a /d/ or dropping the /juː/ glide. Correction tips: keep stress on the first syllable, pronounce /ˈkɒs.tjuːm/ with a light but audible /t/ before the /juː/ and final /m/, and avoid turning it into /ˈkoʊstjuːm/ or /ˈkæs.tuːm/.
US tends to /ˈkɒs.tuːm/ with a rhotic-less or rhotic center depending on speaker; UK often /ˈkɒs.tjuːm/ with a clear /tjuː/ sequence; AU generally mirrors UK with a clipped /ˈkɒs.tjuːm/ and similar /tj/ articulation. The key is the /t/ + /juː/ sequence; some speakers reanalyze /tjuː/ as /tju/ or reduce to /tʃu/ in casual speech. The final /m/ remains closed. Note rhoticity is less relevant here since there’s no rhotic vowel in this word.
It’s challenging because of the /tjuː/ cluster after the stressed syllable, which can blend or reduce into /tuː/ or /tjə/ in fast speech. The mid syllable blends the /s/ and /t/ before the /juː/ glide, and speakers often misplace the stress or elongate the second syllable. Focus on crisp /t/ + /juː/ transition and keep the final /m/ clear to avoid losing the last consonant.
Costume has no silent letters; the challenge is accurate primary stress on the first syllable and the /tjuː/ sequence that should not be reduced to /tuː/ or /tjuː/ with a weak transition. The syllable boundary is toss-up in casual speech, but you should keep it distinct: /ˈkɒs.tjuːm/. This makes your speech clear in performance contexts where intelligibility between characters matters.

Costume comes from the French word costume, which itself derives from the Italian costume meaning ‘costume, attire,’ and ultimately from the Latin consūtus ‘put together, sewn.’ The root is con- ‘together’ + sutus ‘stitched.’ In English, costume originally described clothing appropriate to a character or role (a play, pageant, or masquerade) and later expanded to mean any distinctive clothing for a particular purpose. The shift toward a broader sense of “dress” occurred by the 18th and 19th centuries as theatrical and festive contexts popularized the term. Over time, costume has retained its core meaning—clothing designed to represent a character, era, or theme—while also becoming a general term for outfits created for performances or celebrations. The word’s social associations with theater, disguise, and celebration have influenced its usage in modern English. 200-300 words.
