Present tense conjugation table: influir
Every person of influir in the present tense. The gerund is influyendo and the past participle is influido.
| Person | Form |
|---|---|
| yo | influyo |
| tú | influyes |
| él/ella/Ud. | influye |
| nosotros/as | influimos |
| vosotros/as | influís |
| ellos/ellas/Uds. | influyen |
The gerund is influyendo, which you use with estar to say what is happening right now: “Estoy influyendo” means the action of influir is in progress at this very moment. The past participle is influido, which you use with haber in the perfect tenses: “he influido” is the present perfect, used for a completed action. Keep both forms in mind as you read the examples below, because the present is only one part of how influir is used.
How the present of influir is formed
The present of influir is built from the stem influ plus the present endings for -ir verbs. Take the infinitive, drop the -ir ending, and add the ending that matches the person. The table below shows the endings, and the full table above shows them attached to the stem.
| Person | Ending | Form |
|---|---|---|
| yo | -o | influyo |
| tú | -es | influyes |
| él/ella/Ud. | -e | influye |
| nosotros/as | -imos | influimos |
| vosotros/as | -ís | influís |
| ellos/ellas/Uds. | -en | influyen |
influir is not fully regular in form: this verb is a -uir verb: the stem vowel i becomes y before a vowel ending, so the present is influyo and influye, and the gerund is influyendo. The endings in the table above are the regular -ir endings, so once you know the pattern, the whole tense follows. The forms that show the pattern most clearly are influyo and influye.
The gerund of influir is influyendo and the past participle is influido. Both are the forms you need for the progressive and the perfect tenses with haber.
When to use the present of influir
The present is not a single-purpose tense. Below are the five situations where you will use influir in the present most often. Each one comes with a real example, so read the rule, then say the example out loud.
1. A routine or habit
The present tense of influir is the tense for what happens regularly. When something is part of your routine, your week or your normal life, the present is the right choice, and influir is no exception. The time words that go with it are todos los días, cada semana, siempre and a menudo.
Example: “Influyo en las decisiones de los jóvenes.” — I influence young people's decisions.
2. A general fact
The present tense also states facts that are true in general, not just today. When you describe what influir means in the world — what it does, who it affects, how it works — the present is the tense to use. There is no time limit on the statement, so no past or future form is needed.
Example: “Influye en el resultado de las elecciones.” — He/she influences the result of the elections.
3. Something happening right now
The present tense describes what is happening at this very moment. You do not need the progressive (estar plus the gerund) to say what is going on now: the simple present does the job in Spanish, and it is the more common choice in everyday speech.
Example: “Influyo mucho en mi opinión.” — I influence my opinion a lot.
4. A plan or arrangement
Spanish uses the present tense for plans that are already fixed, especially with a time expression such as mañana or el lunes. When the arrangement is made, the present tense states it as a fact, and influir follows the same rule as every other verb.
Example: “Mañana, nosotros influimos en la salud de la gente.” — Tomorrow, we influence people's health.
5. Asking and answering questions
Questions in the present tense ask about routines, facts and what is happening now. The answer uses the same tense, so a question and its answer stay in the present together. This is the pattern you will hear most often in conversation.
Example: “¿Influyes en el resultado de las elecciones?” — Do you influence the result of the elections?
The present vs the preterite: how to choose
The closest tense to the present is the preterite, and choosing between them is one of the first decisions in Spanish. The rule is simple: the present reports what happens now, what happens regularly, or what is generally true, while the preterite reports one finished action in the past. The three pairs below use the same verb, so the only thing that changes is whether the action is happening now or is already finished. Time words help: ahora and todos los días point to the present, while ayer and anoche point to the preterite.
Present: “Influyo en las decisiones de los jóvenes.” — I influence young people's decisions.
Preterite: “Influí en las decisiones de los jóvenes.” — I influenced young people's decisions.
The present sentence describes what happens now or regularly; the preterite sentence reports one finished action in the past. That difference — now versus finished — is the whole decision.
Present: “Influye en el resultado de las elecciones.” — He/she influences the result of the elections.
Preterite: “Influyó en el resultado de las elecciones.” — He/she influenced the result of the elections.
The present sentence describes what happens now or regularly; the preterite sentence reports one finished action in the past. That difference — now versus finished — is the whole decision.
Present: “Influimos mucho en mi opinión.” — We influence my opinion a lot.
Preterite: “Influimos mucho en mi opinión.” — We influenced my opinion a lot.
The present sentence describes what happens now or regularly; the preterite sentence reports one finished action in the past. That difference — now versus finished — is the whole decision.

Common mistakes with influir in the present
These are the errors learners actually make with this verb in this tense. Each one shows the wrong version, the right version, and why the correction matters.
Wrong: “Yo influye en las decisiones de los jóvenes.” Right: “Yo influyo en las decisiones de los jóvenes.” Why: Yo needs the yo form influyo. The form influye belongs with él, ella or Ud.
Wrong: “Yo influo en el resultado de las elecciones.” Right: “Yo influyo en el resultado de las elecciones.” Why: Influir is a -uir verb: the stem vowel i becomes y before a vowel ending, so the present is influyo and influye, and the gerund is influyendo, so the first-person present is influyo, not influo.
Wrong: “Ayer yo influyo en el resultado de las elecciones.” Right: “Ayer yo influí en el resultado de las elecciones.” Why: The present tense cannot describe a finished action yesterday. Ayer forces the preterite, so the form must change to influí.
Wrong: “Ellos influye en el resultado de las elecciones.” Right: “Ellos influyen en el resultado de las elecciones.” Why: Ellos needs the ellos form influyen. The singular influye belongs with él, ella or a singular noun.
