Gerund: reuniendo · Past participle: reunido

The gerund is reuniendo, which you use with estar to say what is happening right now: “Estoy reuniendo” means the action of reunir is in progress at this very moment. The past participle is reunido, which you use with haber in the perfect tenses: “he reunido” is the present perfect, used for a completed action. Keep both forms in mind as you read the examples below, because the preterite is only one part of how reunir is used.

How the preterite of reunir is formed

reunir is a -ir verb. Take the stem reun and add the preterite endings for -ir verbs: -í, -iste, -ió, -imos, -isteis, -ieron, giving reuní, reuniste, reunió, reunimos, reunisteis and reunieron. reunir is regular in the preterite, so once you know the endings you can build all six forms from the stem. Watch the accents: yo takes an accent on the stressed vowel (reuní) and él takes one too (reunió), because the stress falls on the ending rather than the stem. Note that the nosotros form, reunimos, is identical to the present-tense nosotros form — only context tells you which tense is meant.

The preterite of reunir rewards careful reading of the table. Two details deserve attention. First, the yo form reuní is the form you will use most when you talk about yourself, so say it out loud until it comes without thinking. Second, the nosotros form reunimos and the ellos form reunieron are the ones learners confuse most often, because they are the forms used for groups. Practise the six forms in order — yo, tú, él, nosotros, vosotros, ellos — and the pattern will settle.

When to use the preterite of reunir

The preterite is not a single-purpose tense. Below are the five situations where you will use reunir in the preterite most often. Each one comes with a real example, so read the rule, then say the example out loud.

1. One finished action

reunir in the preterite describes one finished action: something you did and completed. The action is done, and the tense says so. Example: “Yo reuní a los amigos ayer.” — “I gathered the friends.”

2. A sequence of events

When several things happened one after another, each one takes the preterite. The tense moves the story forward, one finished event at a time. Example: “Él reunió a los amigos ayer.” — “He gathered the friends.”

3. An action in a finished time frame

The preterite is the tense of completed actions. When the action started and ended inside a finished period — ayer, anoche, la semana pasada — the preterite is the right choice. Example: “Nosotros reunimos a los amigos la semana pasada.” — “We gathered the friends.”

4. An interruption

When one action interrupted another, the interrupting action takes the preterite. It marks the moment the story changed. Example: “Ellos reunieron a los amigos ayer.” — “They gathered the friends.”

5. A change of state

The preterite also marks a change: the moment something started to be different. If the change itself is the point, use the preterite. Example: “Tú reuniste a los amigos ayer.” — “you gathered the friends.”

Preterite Tense vs Imperfect: how to choose

The closest tense to the preterite is the imperfect, and choosing between them is one of the hardest decisions in Spanish. The rule is simple: the preterite reports one finished action, while the imperfect describes background, habits in the past, or an action that was in progress when something else happened. The three pairs below use the same verb, so the only thing that changes is the tense. Time words help: ayer and de repente point to the preterite, while mientras and todos los días in the past point to the imperfect.

  • Preterite Tense: “Yo reuní a los amigos ayer.” — “I gathered the friends.”

  • Imperfect: “Yo reunía a los amigos cada mañana.” — “I used to gather the friends.”

  • The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: one finished event versus background or a habit in the past. That difference is the whole decision.

  • Preterite Tense: “Él reunió a los amigos ayer.” — “He gathered the friends.”

  • Imperfect: “Él reunía a los amigos cada mañana.” — “He used to gather the friends.”

  • The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: one finished event versus background or a habit in the past. That difference is the whole decision.

  • Preterite Tense: “Nosotros reunimos a los amigos ayer.” — “We gathered the friends.”

  • Imperfect: “Nosotros reuníamos a los amigos cada mañana.” — “We used to gather the friends.”

  • The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: one finished event versus background or a habit in the past. That difference is the whole decision.

Common mistakes

Forgetting the accent in the preterite

The yo preterite form is reuní, with an accent on the stressed vowel. Writing it without the accent — reuni — is a spelling error, and in speech the stress lands in the wrong place. Preterite yo forms that end in a vowel carry that accent, so check it every time you write the preterite of reunir.

Mixing up present and preterite nosotros

For reunir, the nosotros form is the same in the present and the preterite: reunimos. Only the context tells you which tense is meant, so pay attention to the time words around it — cada día points to the present, ayer points to the preterite. Do not invent a different form for one of the tenses.

Confusing reunir with revelar

reunir and revelar look similar, and learners mix them up. They are different verbs with different meanings, so check which one the sentence needs before you conjugate. If you can substitute the English meaning of reunir — gather — the sentence needs reunir; if it needs the meaning of revelar, use that verb instead.

Forgetting the accent in the preterite

The yo preterite form is reuní, with an accent on the stressed vowel. Writing it without the accent — reuni — is a spelling error, and in speech the stress lands in the wrong place. Preterite yo forms that end in a vowel carry that accent, so check it every time you write the preterite of reunir.

Using the wrong tense for reunir

The most general mistake is choosing the wrong tense altogether: using the preterite where Spanish needs the imperfect, or the other way round. Check the time words first — ayer and la semana pasada point to the past, cada día and siempre point to the present — and then check whether the action is finished or ongoing. If you can answer those two questions, the tense usually chooses itself.
