Gerund: entusiasmando · Past participle: entusiasmado

Present Indicative

Person Pronoun Form
yo me entusiasmo
tú te entusiasmas
él/ella/Ud. se entusiasma
nosotros/as nos entusiasmamos
vosotros/as os entusiasmáis
ellos/ellas/Uds. se entusiasman

Use the present of entusiasmarse for things that happen regularly and for things that are true in general. The yo form entusiasmo is the anchor of the table: the other persons follow the regular -ar endings from it. When you talk about yourself right now, this is the form you need.

Preterite

Person Pronoun Form
yo me entusiasmé
tú te entusiasmaste
él/ella/Ud. se entusiasmó
nosotros/as nos entusiasmamos
vosotros/as os entusiasmasteis
ellos/ellas/Uds. se entusiasmaron

Use the preterite of entusiasmarse for a single finished event: something that happened once and is over. The yo form is entusiasmé. If you can put a finished time expression with it — ayer, la semana pasada, anoche — the preterite is usually right.

Imperfect

Person Pronoun Form
yo me entusiasmaba
tú te entusiasmabas
él/ella/Ud. se entusiasmaba
nosotros/as nos entusiasmábamos
vosotros/as os entusiasmabais
ellos/ellas/Uds. se entusiasmaban

Use the imperfect of entusiasmarse for what used to happen and for what was going on when something else happened. The yo form is entusiasmaba. If the action has no clear beginning or end in the story, the imperfect is the right choice.

Future

Person Pronoun Form
yo me entusiasmaré
tú te entusiasmarás
él/ella/Ud. se entusiasmará
nosotros/as nos entusiasmaremos
vosotros/as os entusiasmaréis
ellos/ellas/Uds. se entusiasmarán

Use the future of entusiasmarse for plans, promises and predictions. The yo form is entusiasmaré, built on the infinitive plus the future endings. For a firm plan, the future sounds more formal than ir a + infinitive; for a casual plan, either works.

Conditional

Person Pronoun Form
yo me entusiasmaría
tú te entusiasmarías
él/ella/Ud. se entusiasmaría
nosotros/as nos entusiasmaríamos
vosotros/as os entusiasmaríais
ellos/ellas/Uds. se entusiasmarían

Use the conditional of entusiasmarse for hypothetical situations and for softening requests. The yo form is entusiasmaría. It appears after si-clauses with the imperfect subjunctive and on its own for polite suggestions.

Present Perfect

Person Pronoun Form
yo me he entusiasmado
tú te has entusiasmado
él/ella/Ud. se ha entusiasmado
nosotros/as nos hemos entusiasmado
vosotros/as os habéis entusiasmado
ellos/ellas/Uds. se han entusiasmado

Use the present perfect of entusiasmarse for recent events with present relevance. The yo form is he entusiasmado — haber in the present plus entusiasmado. Time expressions like hoy, esta semana and últimamente are its natural partners.

Pluperfect

Person Pronoun Form
yo me había entusiasmado
tú te habías entusiasmado
él/ella/Ud. se había entusiasmado
nosotros/as nos habíamos entusiasmado
vosotros/as os habíais entusiasmado
ellos/ellas/Uds. se habían entusiasmado

Use the pluperfect of entusiasmarse when you need two layers of past: one event already finished before another past event began. The yo form is había entusiasmado. It is the tense of «had already done».

Future Perfect

Person Pronoun Form
yo me habré entusiasmado
tú te habrás entusiasmado
él/ella/Ud. se habrá entusiasmado
nosotros/as nos habremos entusiasmado
vosotros/as os habréis entusiasmado
ellos/ellas/Uds. se habrán entusiasmado

Use the future perfect of entusiasmarse to say that something will be finished by a future moment. The yo form is habré entusiasmado. It pairs naturally with deadlines: para mañana, para el viernes, para entonces.

Conditional Perfect

Person Pronoun Form
yo me habría entusiasmado
tú te habrías entusiasmado
él/ella/Ud. se habría entusiasmado
nosotros/as nos habríamos entusiasmado
vosotros/as os habríais entusiasmado
ellos/ellas/Uds. se habrían entusiasmado

Use the conditional perfect of entusiasmarse for the past that did not happen: what would have been done with more time or a different choice. The yo form is habría entusiasmado. It follows si-clauses with the pluperfect subjunctive.

Present Subjunctive

Person Pronoun Form
yo me entusiasme
tú te entusiasmes
él/ella/Ud. se entusiasme
nosotros/as nos entusiasmemos
vosotros/as os entusiasméis
ellos/ellas/Uds. se entusiasmen

Use the present subjunctive of entusiasmarse when the main clause expresses a wish, a doubt, an emotion or an impersonal judgement. The yo form is entusiasme. After espero que, ojalá que and no creo que, the subjunctive is required, not optional.

Imperfect Subjunctive (-ra forms)

Person Pronoun Form
yo me entusiasmara
tú te entusiasmaras
él/ella/Ud. se entusiasmara
nosotros/as nos entusiasmáramos
vosotros/as os entusiasmarais
ellos/ellas/Uds. se entusiasmaran

Use the imperfect subjunctive of entusiasmarse after past-tense wishes and doubts, and in si-clauses that set up a hypothetical present. The yo form is entusiasmara. It is built on the third-person plural preterite stem, which is why it looks different from the present subjunctive.

Imperative — Affirmative

Person Pronoun Form
tú te entusiasma
él/ella/Ud. se entusiasme
nosotros/as nos entusiasmemos
vosotros/as os entusiasmad
ellos/ellas/Uds. se entusiasmen

There is no yo form in the imperative — you cannot command yourself.

In real speech the reflexive pronoun attaches to the end of an affirmative command; the table shows the pronoun and the form separately so you can see both parts.

Use the affirmative imperative of entusiasmarse to tell someone to do something: instructions, invitations and requests. The tú form is entusiasma. For a polite command, use the usted form entusiasme instead of the tú form.

Imperative — Negative

Person Pronoun Form
tú te entusiasmes
él/ella/Ud. se entusiasme
nosotros/as nos entusiasmemos
vosotros/as os entusiasméis
ellos/ellas/Uds. se entusiasmen

There is no yo form in the imperative — you cannot command yourself.

In real speech the reflexive pronoun attaches to the end of an affirmative command; the table shows the pronoun and the form separately so you can see both parts.

Use the negative imperative of entusiasmarse to forbid or to warn: «¡No entusiasmes!». The tú form is entusiasmes, taken from the present subjunctive. The word no always comes first, and the form never changes for emphasis.

Example sentences

  1. Me entusiasmo todos los días. — I get excited every day.

  4. Mañana me entusiasmaré sin falta. — Tomorrow I will get excited without fail.
  5. Si tuviera más tiempo, me entusiasmaría ahora mismo. — If I had more time, I would get excited right now.
  6. Hoy me he entusiasmado dos veces. — Today I have got excited twice.
  7. Espero que te entusiasmes pronto. — I hope You get excited soon.
  8. Si me entusiasmara, todo sería distinto. — If I got excited, everything would be different.

  10. ¡No te entusiasmes! — Don't get excited!

Common mistakes

1. Forgetting the reflexive pronoun

Wrong: yo entusiasmo todos los días.

Right: me entusiasmo todos los días.

entusiasmarse is reflexive: the pronoun me belongs before every conjugated form. Without it, you are using the non-reflexive verb, which means something different — doing the action to someone else instead of to yourself.

2. Using the imperfect for a finished event

Wrong: Ayer me entusiasmaba.

Right: Ayer me entusiasmé.

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

3. Using the indicative after a subjunctive trigger

Wrong: Espero que te entusiasmas.

Right: Espero que te entusiasmes.

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

4. Using the affirmative imperative after no

Wrong: No te entusiasma.

Right: No te entusiasmes.

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

5. Confusing the gerund with the past participle

Wrong: He entusiasmando.

Right: He entusiasmado.

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

Frequently asked questions

Is entusiasmarse regular or irregular?

Yes — entusiasmarse is a regular -ar verb and reflexive. Learn the endings once and they work in every tense, with the stem entusiasm unchanged throughout.

What are the gerund and past participle of entusiasmarse?

The gerund is entusiasmando and the past participle is entusiasmado. Use the gerund with estar for actions in progress («Estoy entusiasmando») and the participle with haber for the perfect tenses («he entusiasmado»).

How do I say «I get excited» in Spanish?

Say «Me entusiasmo todos los días». That is the yo form of the present tense, the form you need for talking about yourself right now.

What is the difference between the preterite and the imperfect of entusiasmarse?

Use the preterite (entusiasmé) for a single finished event and the imperfect (entusiasmaba) for habits and background. «Ayer yo entusiasmé» reports something that happened and ended; «Antes, yo entusiasmaba» describes what used to happen.

When do I use the subjunctive with entusiasmarse?

Use the subjunctive after wishes, doubts, emotions and impersonal expressions — for example «Espero que tú entusiasmes». The trigger sits in the main clause; once it is there, the subjunctive form is required, not a stylistic choice.

What does the -se in entusiasmarse mean?

The -se marks entusiasmarse as reflexive: the action comes back to the subject. You always pair the form with its pronoun — me, te, se, nos, os, se — placed before the conjugated verb. Dropping the pronoun changes the meaning, so treat the pronoun as part of the verb.
