The present tense vs the preterite

Learners often mix up the present and the preterite with unificar. The rule is simple: the present is for habits, facts and what is happening now, while the preterite is for one finished action in the past. The three pairs below show the same idea in both tenses, so you can feel the difference.

Pair 1: present vs preterite

  • Present: "Yo unifico los dos departamentos." — "I unify the two departments."
  • Preterite: "Yo unifiqué los dos departamentos." — "I unified the two departments." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Pair 2: present vs preterite

  • Present: "Él unifica los criterios de la empresa." — "He/she unifies the company's criteria."
  • Preterite: "Él unificó los criterios de la empresa." — "He/she unified the company's criteria." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Pair 3: present vs preterite

  • Present: "Nosotros unificamos las normas de los países." — "We unify the countries' rules."
  • Preterite: "Nosotros unificamos las normas de los países." — "We unified the countries' rules." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Common mistakes

  1. Wrong: Vosotros unificais los criterios de la empresa. — Right: Vosotros unificáis los criterios de la empresa. — The vosotros present form carries a written accent: unificáis, not unificais.
  2. Wrong: Ayer, yo unifico las normas de los países. — Right: Ayer, yo unifiqué las normas de los países. — Ayer means yesterday, so it needs the preterite (unifiqué), not the present (unifico). The present is for now, not for yesterday.
  3. 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.
  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. Ser plus the participle makes a passive, not a perfect tense.
