Casar Conjugation in Spanish
The Spanish verb casar means to marry (someone off), and it is a verb you will use again and again once you know it. Casar means to marry someone off, and it is the transitive verb for marrying a daughter, a son or a couple: parents marry their daughter in June, a priest marries the couple in church.

Common mistakes
- Wrong: Yo casa a su hija en junio. — Right: Yo caso a su hija en junio. — The person matters: casa is the él/ella/Ud. form, while the yo form is caso. Using the third-person form with yo is one of the most common beginner errors.
- Wrong: Treating casar and casarse as identical in every context. — Right: Casar means to marry (someone off), while casarse means to get married yourself. — They overlap, but each has uses the other does not: casar fits sentences such as Caso a su hija en junio, while casarse belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy casado a los novios en la iglesia. — Right: Yo he casado a los novios en la iglesia. — Spanish perfect tenses use haber, not ser: he casado, has casado, ha casado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo casé a su hijo con una vecina todos los días. — Right: De niño, yo casaba a su hijo con una vecina todos los días. — For a repeated habit in the past, use the imperfect (casaba), not the preterite. The preterite (casé) is for one finished action.
