Q: How do you pronounce cien in Spanish?

cien is pronounced with the stress described below. In IPA it is written /sjen/. It means “one hundred.” syen, one syllable, opening with an s sound — not a k, and not two beats.

syen, one syllable, opening with an s sound — not a k, and not two beats.

cien /sjen/

Only one syllable, so the stress rule has nothing to choose between. Worth knowing that "cien" is the shortened form used directly before a noun; the full "ciento" adds a syllable and stresses CIEN-to, second-to-last, per the usual rule. Neither form takes an accent.

Sound it out

ci Before an e, the c is a plain "s" in Latin American Spanish. The i then glides straight on as a y sound, so this is "sy-", not "see-".

en A short "eh" as in "bed", closed with a clean n. The whole word is one beat: s-y-eh-n, said as fast as English "yen" with an s in front.

"El libro cuesta cien pesos" uses the short form because a noun follows immediately — say "ciento" here and it sounds wrong to a native ear. "Cuesta" opens with the same hard-c-plus-glide you met in "cuatro", KWEHS-ta, and gives a nice contrast within one sentence: the c in "cuesta" is a k, the c in "cien" is an s, decided purely by the vowel that follows.

Where English speakers slip

English speakers reading this cold often produce "kyen" or "see-EN". Both halves need fixing: the c is soft because an e follows it, and the ie is a single glide rather than two vowels. There is also a meaning trap worth flagging — "cien" is exactly one hundred, while "cientos" means hundreds, and mixing them up in a shop is more expensive than mispronouncing either.
