Common mistakes with alegrarse

The errors learners actually make with alegrarse, each with the wrong form, the right form, and why the right form is right.

✗ *Yo alegro de la noticia (dropping the pronoun).

✓ Correct: Yo me alegro de la noticia.

Alegrarse is reflexive: me alegro. Yo alegro means "I make (someone) glad".

✗ *Nosotros alegramos por ti (missing nos).

✓ Correct: Nosotros nos alegramos por ti.

The pronoun is obligatory: nos alegramos, not alegramos.

✗ *Tú alegras de la buena noticia (missing te).

✓ Correct: Tú te alegras de la buena noticia.

Again, the pronoun is part of the verb: te alegras.

✗ *Vosotros alegráis de la victoria (missing os).
