Common mistakes

  1. Wrong: Yo adhiero a la huelga general. — Right: Yo me adhiero a la huelga general. — Adherirse is reflexive, so the pronoun me is required: without it the verb means something else, or nothing at all.
  2. Wrong: Yo adhero al acuerdo de paz. — Right: Yo adhiero al acuerdo de paz. — Adherirse is a stem-changing verb (e → ie), so the stem changes in the present singular and third-person plural. The nosotros form keeps the original stem.
  3. Wrong: Treating adherirse and pegarse as identical in every context. — Right: Adherirse means to adhere, to stick to, while pegarse means to stick, physically. — They overlap, but each has uses the other does not: adherirse fits sentences such as Me adhiero a la huelga general, while pegarse belongs in a different sentence. Check the meaning you want before choosing.
  4. Wrong: Yo soy adherido al acuerdo de paz. — Right: Yo he adherido al acuerdo de paz. — Spanish perfect tenses use haber, not ser: he adherido, has adherido, ha adherido. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: De niño, yo adherí a la pared con pegamento todos los días. — Right: De niño, yo adhería a la pared con pegamento todos los días. — For a repeated habit in the past, use the imperfect (adhería), not the preterite. The preterite (adherí) is for one finished action.

Frequently asked questions

What does adherirse mean in English?

Adherirse means to adhere, to stick to. It is used in everyday situations such as Me adhiero a la huelga general. The exact English wording depends on the context, but the core meaning stays the same across the tenses.

Is adherirse a reflexive verb?

Yes. Adherirse is reflexive, so it always takes a reflexive pronoun that matches the person: me, te, se, nos, os or se. For example, Me adhiero a la huelga general and él se adhiere al acuerdo de paz. If you leave the pronoun out, the verb changes meaning or stops making sense.

What is the difference between adherirse and pegarse?

Adherirse means to adhere, to stick to, while pegarse means to stick, physically. They are easy to confuse because they appear in similar situations, but they are not interchangeable: use adherirse when you mean to adhere, to stick to, as in Me adhiero a la huelga general, and use pegarse for to stick, physically. When in doubt, check the object of the sentence — it usually shows which verb fits.

How do I say “I adhere” in the past?

It depends on the kind of past. For one finished action, use the preterite: yo me adherí al acuerdo de paz. For a repeated habit or background in the past, use the imperfect: yo me adhería a la pared con pegamento. For something that has just happened, use the present perfect: yo me he adherido al acuerdo de paz.

How do I practise adherirse?

Start with the present tense table, then drill the preterite and the imperfect, since those two past tenses cause the most mistakes. Try the adherirse examples and quiz page for more sentences, and use the Spanish Verb Quiz to test the forms under pressure.
