Full conjugation tables

Every form below comes from the verified conjugation tables for llenar. The imperfect subjunctive is shown in its -ra forms; the -se forms use the same stem.

Gerund: llenando · Past participle: llenado

Present Indicative

Person Form
yo lleno
tú llenas
él/ella/Ud. llena
nosotros/as llenamos
vosotros/as llenáis
ellos/ellas/Uds. llenan

Use the present of llenar for things that happen regularly and for things that are true in general. The yo form lleno 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 Form
yo llené
tú llenaste
él/ella/Ud. llenó
nosotros/as llenamos
vosotros/as llenasteis
ellos/ellas/Uds. llenaron

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

Imperfect

Person Form
yo llenaba
tú llenabas
él/ella/Ud. llenaba
nosotros/as llenábamos
vosotros/as llenabais
ellos/ellas/Uds. llenaban

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

Future

Person Form
yo llenaré
tú llenarás
él/ella/Ud. llenará
nosotros/as llenaremos
vosotros/as llenaréis
ellos/ellas/Uds. llenarán

Use the future of llenar for plans, promises and predictions. The yo form is llenaré, 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 Form
yo llenaría
tú llenarías
él/ella/Ud. llenaría
nosotros/as llenaríamos
vosotros/as llenaríais
ellos/ellas/Uds. llenarían

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

Present Perfect

Person Form
yo he llenado
tú has llenado
él/ella/Ud. ha llenado
nosotros/as hemos llenado
vosotros/as habéis llenado
ellos/ellas/Uds. han llenado

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

Pluperfect

Person Form
yo había llenado
tú habías llenado
él/ella/Ud. había llenado
nosotros/as habíamos llenado
vosotros/as habíais llenado
ellos/ellas/Uds. habían llenado

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

Future Perfect

Person Form
yo habré llenado
tú habrás llenado
él/ella/Ud. habrá llenado
nosotros/as habremos llenado
vosotros/as habréis llenado
ellos/ellas/Uds. habrán llenado

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

Conditional Perfect

Person Form
yo habría llenado
tú habrías llenado
él/ella/Ud. habría llenado
nosotros/as habríamos llenado
vosotros/as habríais llenado
ellos/ellas/Uds. habrían llenado

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

Present Subjunctive

Person Form
yo llene
tú llenes
él/ella/Ud. llene
nosotros/as llenemos
vosotros/as llenéis
ellos/ellas/Uds. llenen

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

Imperfect Subjunctive (-ra forms)

Person Form
yo llenara
tú llenaras
él/ella/Ud. llenara
nosotros/as llenáramos
vosotros/as llenarais
ellos/ellas/Uds. llenaran

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

Imperative — Affirmative

Person Form
tú llena
él/ella/Ud. llene
nosotros/as llenemos
vosotros/as llenad
ellos/ellas/Uds. llenen

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

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

Imperative — Negative

Person Form
tú llenes
él/ella/Ud. llene
nosotros/as llenemos
vosotros/as llenéis
ellos/ellas/Uds. llenen

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

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

Example sentences

  1. Yo lleno todos los días. — I fill every day.
  2. Ayer yo llené por la tarde. — Yesterday I filled in the afternoon.
  3. Antes, yo llenaba todos los días. — In the past, I used to fill every day.
  4. Mañana yo llenaré sin falta. — Tomorrow I will fill without fail.
  5. Si tuviera más tiempo, yo llenaría ahora mismo. — If I had more time, I would fill right now.
  6. Hoy yo he llenado dos veces. — Today I have filled twice.
  7. Espero que tú llenes pronto. — I hope You fill soon.
  8. Si yo llenara, todo sería distinto. — If I filled, everything would be different.
  9. Ahora mismo yo estoy llenando. — Right now I am filling.
  10. ¡llena, por favor! — Fill, please!

Common mistakes

1. Using the imperfect for a finished event

Wrong: Ayer yo llenaba.

Right: Ayer yo llené.

Yesterday's finished action needs the preterite, llené. The imperfect llenaba 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 llenas.

Right: Espero que tú llenes.

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

3. Using the affirmative imperative after no

Wrong: No llena.

Right: No llenes.

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

4. Using the infinitive instead of a conjugated form

Wrong: Yo llenar todos los días.

Right: Yo lleno todos los días.

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

5. Confusing the gerund with the past participle

Wrong: He llenando.

Right: He llenado.

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

Frequently asked questions

Is llenar regular or irregular?

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

What are the gerund and past participle of llenar?

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

How do I say «I fill» in Spanish?

Say «Yo lleno 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 llenar?

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

When do I use the subjunctive with llenar?

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

How do I use llenar in the present perfect?

Put haber in the present before the past participle: «Hoy yo he llenado». The participle llenado never changes for person — only haber changes — so once you know the participle, the whole perfect tense follows.
