Spanish · Pronunciation Guide
SEEN-koh. The first c is an s, the second is a hard k — same letter, two jobs.
Two syllables, CIN-co, weight on the first. Ending in a vowel puts it squarely under the default rule, so no accent is written. The pattern holds when the word grows: "cincuenta" moves the beat to cin-CUEN-ta, again the second-to-last syllable, and again unmarked.

"El boleto cuesta cinco pesos" is worth hearing as a chain of s sounds — cuesta, cinco, pesos — every one of them a clean hiss with no z buzz anywhere. "Cuesta" also repeats the ue glide you met in "buenos": KWEHS-ta, one beat for the first syllable.
The two c's are the puzzle. Learners either make both hard ("KEEN-ko") or both soft ("SEEN-so"), when Spanish assigns them by the following letter: c before e or i is s, c before a, o or u is k. Once you know the rule, "cinco" becomes a useful test word. A separate note for travelers: in most of Spain that first c is pronounced like the th of "think", but the s pronunciation used across Latin America is understood universally.
