Unificar in context

Two short dialogues that use unificar the way people really use it. Read them aloud — the verb forms will stick much faster in a conversation than in a table.

Dialogue 1: today and yesterday

  • Ana: "Hola, ¿qué tal?" — "Hello, how are you?"
  • Luis: "Hoy unifico los dos departamentos." — "Today I unify the two departments."
  • Ana: "¿Y ayer?" — "And yesterday?"
  • Luis: "Ayer, unifiqué las normas de los países." — "Yesterday I unified the countries' rules."
  • Ana: "¿Y mañana, tú unificarás los criterios de la empresa?" — "And tomorrow, will you will unify the company's criteria?"
  • Luis: "Sí, claro. Y tú también." — "Yes, of course. And you too."

Dialogue 2: making plans

  • Marta: "Mañana, nosotros unificamos los horarios de las clases." — "Tomorrow we unify the class timetables."
  • Carlos: "Perfecto. Yo unificaría los criterios de la empresa si tuviera más tiempo." — "Perfect. I would would unify the company's criteria if I had more time."
  • Marta: "Espero que él unifique los dos departamentos." — "I hope he unifies the two departments."
  • Carlos: "Seguro que sí. Él ya ha unificado las normas de los países." — "Surely. He has already has unified the countries' rules."
  • Marta: "Vale, nos vemos mañana." — "OK, see you tomorrow."

Notice how the same verb changes with the tense: the present for the plan, the conditional for the wish, the subjunctive after espero que, and the present perfect for what has already happened. That is the whole point of learning a verb across its tenses, not just in one form.

Common mistakes

  1. Wrong: Yo unifica los dos departamentos. — Right: Yo unifico los dos departamentos. — The person matters: unifica is the él/ella/Ud. form, while the yo form is unifico. Using the third-person form with yo is one of the most common beginner errors.
  2. Wrong: Yo unificé los criterios de la empresa. — Right: Yo unifiqué los criterios de la empresa. — In the preterite, the correct first-person form is unifiqué, not unificé. unificar is a spelling-change verb: c becomes qu before e, so the written form changes to keep the same sound. The regular-looking form is wrong.
  3. Wrong: Treating unificar and unir as identical in every context. — Right: Unificar means to unify, while unir means to join, the simple verb. — They overlap, but each has uses the other does not: unificar fits sentences such as Unifico los dos departamentos, while unir belongs in a different sentence. Check the meaning you want before choosing.
  4. Wrong: Yo soy unificado los criterios de la empresa. — Right: Yo he unificado los criterios de la empresa. — Spanish perfect tenses use haber, not ser: he unificado, has unificado, ha unificado. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: De niño, yo unifiqué las normas de los países todos los días. — Right: De niño, yo unificaba las normas de los países todos los días. — For a repeated habit in the past, use the imperfect (unificaba), not the preterite. The preterite (unifiqué) is for one finished action.
