  3. Wrong: Treating achacar and culpar as identical in every context. — Right: Achacar means to blame, to attribute, while culpar means to blame someone. — They overlap, but each has uses the other does not: achacar fits sentences such as Achaco la culpa a su compañero, while culpar belongs in a different sentence. Check the meaning you want before choosing.
  4. Wrong: Yo soy achacado el error al cansancio. — Right: Yo he achacado el error al cansancio. — Spanish perfect tenses use haber, not ser: he achacado, has achacado, ha achacado. Ser plus the participle makes a passive, not a perfect tense.

Frequently asked questions

What does achacar mean in English?

Achacar means to blame, to attribute. It is used in everyday situations such as Achaco la culpa a su compañero. The exact English wording depends on the context, but the core meaning stays the same across the tenses.

Is achacar regular or irregular?

Achacar is a spelling-change verb, so it is not fully regular. Spelling change: c becomes qu before e, so the present subjunctive is achaque and the preterite first person is achaqué — the sound stays the same, only the spelling changes. The other tenses follow the regular -ar endings. Learn the changed forms from the tables above rather than applying the regular spelling.

What is the difference between achacar and culpar?

Achacar means to blame, to attribute, while culpar means to blame someone. They are easy to confuse because they appear in similar situations, but they are not interchangeable: use achacar when you mean to blame, to attribute, as in Achaco la culpa a su compañero, and use culpar for to blame someone. When in doubt, check the object of the sentence — it usually shows which verb fits.

How do I say “I blame” in the past?

It depends on the kind of past. For one finished action, use the preterite: yo achaqué el error al cansancio. For a repeated habit or background in the past, use the imperfect: yo achacaba el problema a la falta de tiempo. For something that has just happened, use the present perfect: yo he achacado el error al cansancio.

How do I practise achacar?

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