Common mistakes

  1. Wrong: Yo aglomera a la gente en la plaza. — Right: 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.
  2. Wrong: Ayer yo aglomero los papeles sobre la mesa. — Right: 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.
  3. Wrong: Treating aglomerar and reunir as identical in every context. — Right: 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.
  4. Wrong: Yo soy aglomerado los papeles sobre la mesa. — Right: 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.
  5. Wrong: De niño, yo aglomeré a los coches en la carretera todos los días. — Right: 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.
