Common mistakes with aglomerar

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

✗ Yo aglomera a la gente en la plaza.

✓ Correct: Yo aglomero a la gente en la plaza.

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

✗ Ayer yo aglomero los papeles sobre la mesa.

✓ Correct: Ayer yo aglomeré los papeles sobre la mesa.

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

✗ Treating aglomerar and reunir as identical in every context.

✓ Correct: Aglomerar means to pile up, to crowd together, while reunir means to gather people.

They overlap, but each has uses the other does not: aglomerar fits sentences such as Aglomero a la gente en la plaza, while reunir belongs in a different sentence. Check the meaning you want before choosing.

✗ Yo soy aglomerado los papeles sobre la mesa.

✓ Correct: Yo he aglomerado los papeles sobre la mesa.

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

✗ De niño, yo aglomeré a los coches en la carretera todos los días.

✓ Correct: De niño, yo aglomeraba a los coches en la carretera todos los días.

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