Common mistakes with ajustarse

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

✗ Yo ajusto a las normas de la empresa.

✓ Correct: Yo me ajusto a las normas de la empresa.

Ajustarse is reflexive, so the pronoun me is required: without it the verb means something else, or nothing at all.

✗ Ayer yo ajusto al presupuesto del mes.

✓ Correct: Ayer yo ajusté al presupuesto del mes.

The present and the preterite are different tenses: ajusto is happening now, while ajusté is a finished action in the past. Use the preterite with ayer.

✗ Treating ajustarse and adaptarse as identical in every context.

✓ Correct: Ajustarse means to adjust (oneself), to fit, while adaptarse means to adapt oneself.

They overlap, but each has uses the other does not: ajustarse fits sentences such as Me ajusto a las normas de la empresa, while adaptarse belongs in a different sentence. Check the meaning you want before choosing.

✗ Yo soy ajustado al presupuesto del mes.

✓ Correct: Yo he ajustado al presupuesto del mes.

Spanish perfect tenses use haber, not ser: he ajustado, has ajustado, ha ajustado. Ser plus the participle makes a passive, not a perfect tense.

✗ De niño, yo ajusté el vestido a su cuerpo todos los días.

✓ Correct: De niño, yo ajustaba el vestido a su cuerpo todos los días.

For a repeated habit in the past, use the imperfect (ajustaba), not the preterite. The preterite (ajusté) is for one finished action.
