How to Use 'Reír' and 'Reírse'

Two Forms of Verb Usually Mean Same Thing

Is there a difference in meaning between reír and reírse? Dictionaries give the same definition for both. The two verbs, which mean "to laugh," mean basically the same thing. Although you will find some regional variations, reírse is the more common of the two. Thus, while reí would be understood to mean "I laughed," it would be more common to say me reí. Reír can sometimes sound poetic or somewhat old-fashioned.

Note that reír and reírse are conjugated irregularly.

When Reír or Reírse Is Required

There are at least two cases where one form is required:

When followed by de, the reflexive form reírse usually means "to make fun of" or "to laugh at":

  • Me reía de mi hermano, pero ahora somos amigos. (I used to make fun of my brother, but now we're friends.)
  • Se reirán de su falta de sofisticación computarizada. (They will laugh at your lack of computer sophistication.)
  • Me quiero reír de mí mismo. (I want to laugh at myself.)

If you are talking about what makes a person laugh, the reflexive form isn't used. Hacer is typically used as the verb for "to make":

  • Me hace reír cuando estoy triste. (She makes me laugh when I'm sad.)
  • Austin Powers no me hizo reír más de una vez. (Austin powers didn't make me laugh more than once.)
  • Ayer me hiciste daño y hoy me vas a hacer reír. (Yesterday you hurt me and today you're going to make me laugh.)

There's no logical reason why reírse de is used to mean "to laugh at" rather than reírse a or even reírse en. That's just the way it is. This is one of those cases where you should learn the preposition along with the verb.
