Spelling it as "trese"

The correct spelling uses a "c" before the final "e": "trece." Writing it with an "s" is a common phonetic mistake because the "ce" sounds like "se" in Latin American Spanish.

Confusing "trece" (13) with "tres" (3)

Incorrect: Necesito tres botellas. (meaning 13)

Correct: Necesito trece botellas.

"Tres" is 3 and "trece" is 13. They sound similar, especially to beginners. Pronounce the second syllable clearly—TREH-seh—to avoid confusion.

Common Questions About 13 in Spanish

Is 13 considered unlucky in Spanish-speaking countries?
In Spain, the unlucky day is Tuesday the 13th (martes trece), not Friday the 13th as in English-speaking countries. The saying goes: "En martes, ni te cases ni te embarques" (On Tuesday, neither marry nor set sail). In Latin America, superstitions vary by country.
Does "trece" change form for masculine or feminine nouns?
Trece is completely invariable—it never changes for gender or number. You say trece libros and trece sillas with the exact same form, just like most cardinal numbers in Spanish.
How do I say "thirteenth" as an ordinal in Spanish?
The ordinal is "decimotercero" (masculine) or "decimotercera" (feminine). In practice, ordinals this high are rarely used in conversation; Spanish speakers prefer the cardinal form, saying "el piso trece" rather than "el decimotercer piso."
