Fumar Examples, Sentences & Quiz

Introduction

fumar means to smoke, and it is one of those verbs that shows up everywhere once you start listening for it. It is a regular -ar verb verb, and this page puts it to work: real example sentences in several tenses, grouped by use, two short passages that show the verb in context, the mistakes learners make with it, a ten-question quiz and answers to common questions. If you only learn one sentence, make it «Yo fumo todos los días» — I smoke every day. The rest of this page builds out from there, tense by tense, so you can use fumar the way native speakers do — in the present for habits, in the past for finished events, and in the subjunctive after wishes and doubts.

Fumar in real example sentences

In the present: everyday use

The present is where fumar lives most of the time — routines, facts and what is happening now:

  1. Yo fumo todos los días. — I smoke every day.
  2. Tú fumas en el trabajo. — You smoke at work.
  3. Él fuma con mi familia. — He smokes with my family.
  4. Nosotros fumamos por la mañana. — We smoke in the morning.

Talking about the past

In the past, choose the preterite for a finished event and the imperfect for a habit or background:

  1. Ayer yo fumé por la tarde. — Yesterday I smoked in the afternoon.
  2. Antes, yo fumaba todos los días. — In the past, I used to smoke every day.
  3. La semana pasada él fumó dos veces. — Last week He smoked twice.

Plans and things already done

The future, the conditional and the present perfect round out the picture — plans, hypotheticals and recent events:

  1. Mañana yo fumaré sin falta. — Tomorrow I will smoke without fail.
  2. Si tuviera más tiempo, yo fumaría ahora mismo. — If I had more time, I would smoke right now.
  3. Hoy yo he fumado dos veces. — Today I have smoked twice.

More everyday uses

The subjunctive, the imperative and the progressive cover wishes, commands and actions in progress:

  1. Espero que tú fumes pronto. — I hope You smoke soon.
  2. ¡fuma, por favor! — Smoke, please!
  3. Ahora mismo yo estoy fumando. — Right now I am smoking.

Fumar in context

A short dialogue

Ana: «Yo fumo en el trabajo.» — I smoke at work. Luis: «¡Qué bien! Yo fumo con mi familia.» — I smoke with my family. Ana: «Mañana yo fumaré sin falta.» — Tomorrow I will smoke without fail.

A short paragraph

Ayer yo fumé por la tarde. Antes, yo fumaba todos los días. Hoy yo he fumado dos veces. Mañana yo fumaré sin falta.

Yesterday I smoked in the afternoon. In the past, I used to smoke every day. Today I have smoked twice. Tomorrow I will smoke without fail.

Common mistakes with fumar

1. Using the imperfect for a finished event

Wrong: Ayer yo fumaba.

Right: Ayer yo fumé.

Yesterday's finished action needs the preterite, fumé. The imperfect fumaba describes what used to happen or what was going on, not a single completed event.

2. Using the indicative after a subjunctive trigger

Wrong: Espero que tú fumas.

Right: Espero que tú fumes.

After espero que, Spanish requires the subjunctive: fumes, not the indicative fumas. Wishes, hopes and doubts all trigger this change.

3. Using the affirmative imperative after no

Wrong: No fuma.

Right: No fumes.

Negative commands use the subjunctive-based forms: no fumes. The affirmative fuma can never follow no.

4. Using the infinitive instead of a conjugated form

Wrong: Yo fumar todos los días.

Right: Yo fumo todos los días.

The infinitive fumar names the action; it never works as the main verb of a sentence. Conjugate it for the person: yo fumo.

5. Confusing the gerund with the past participle

Wrong: He fumando.

Right: He fumado.

The perfect tenses use haber plus the past participle: he fumado. The gerund fumando goes with estar for actions in progress («Estoy fumando»), never with haber.

Frequently asked questions

How do you say 'I smoke' in Spanish?

Say «Yo fumo todos los días». That is the present-tense yo form, and it is the sentence you will use most with this verb.

How do you say 'I smoked' about yesterday?

Say «Ayer yo fumé por la tarde». The preterite is the tense for a finished event: yesterday, last week, last night.

Is fumar reflexive?

No — fumar is not reflexive. It conjugates without a pronoun: yo fumo, tú fumas, él fuma. If you see a -se form of a similar verb, that is a different verb with its own meaning.

Which tense do learners find hardest with fumar?

Most learners struggle with choosing between the preterite and the imperfect, not with the forms themselves. Use the preterite (fumé) for a single finished event and the imperfect (fumaba) for habits and background. After that, the subjunctive is the next step.
