How to Say "Twin" in Spanish

Gemelo · noun · heh-MEH-loh

Gemelo is the primary Spanish word for "twin." Strictly speaking, gemelo refers to an identical twin and mellizo to a fraternal twin, but in casual conversation gemelo often covers both. The word changes for gender: gemelo (masculine) and gemela (feminine). In Mexico, cuate is a colloquial term for a twin or a very close friend.

heh-MEH-loh (masculine); heh-MEH-lah (feminine)

Avoid These Mistakes When Using Gemelo

Using gemelo for cufflinks without context

Incorrect: Compré unos gemelos bonitos para mi hermano. (intending twins)

Correct: Mi hermano tiene gemelos. (He has twin children.) / Compré unos gemelos bonitos. (I bought nice cufflinks.)

Gemelos can also mean "cufflinks" in Spanish (especially in Spain). Context usually clarifies the meaning, but be aware of the double sense.

Forgetting gender agreement

Incorrect: Ella es mi gemelo.

Correct: Ella es mi gemela.

Gemelo changes to gemela when referring to a female twin. The adjective must agree in gender with the person it describes.
