Common mistakes with acoplar

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

✗ Yo acopla el remolque al coche.

✓ Correct: Yo acoplo el remolque al coche.

The person matters: acopla is the él/ella/Ud. form, while the yo form is acoplo. Using the third-person form with yo is one of the most common beginner errors.

✗ Ayer yo acoplo las piezas del mueble.

✓ Correct: Ayer yo acoplé las piezas del mueble.

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

✗ Treating acoplar and ajustar as identical in every context.

✓ Correct: Acoplar means to fit together, to couple, while ajustar means to adjust.

They overlap, but each has uses the other does not: acoplar fits sentences such as Acoplo el remolque al coche, while ajustar belongs in a different sentence. Check the meaning you want before choosing.

✗ Yo soy acoplado las piezas del mueble.

✓ Correct: Yo he acoplado las piezas del mueble.

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

✗ De niño, yo acoplé el vagón a la locomotora todos los días.

✓ Correct: De niño, yo acoplaba el vagón a la locomotora todos los días.

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