How to use each tense

Present indicative

Use the present for routines, general facts and what is happening right now. It is the tense you will use most often in everyday conversation, for habits with words like todos los días and for statements that are true in general. For poseer, the present indicative looks like this in a real sentence: Yo poseo mucho dinero — "I possess a lot of money". Learn the present indicative forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Preterite

Use the preterite for finished actions in the past — things that started and ended, often with time words like ayer, anoche or la semana pasada. The preterite moves a story forward, one completed event at a time. For poseer, the preterite looks like this in a real sentence: Yo poseí un coche nuevo — "I possessed a new car". Learn the preterite forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense. This is a vowel-stem verb: the third-person preterite and the gerund use y, as in poseyó and poseyendo.

Imperfect

Use the imperfect for background, habits and actions in progress in the past, often with words like antes, de niño or mientras. It describes how things used to be, not one finished event. For poseer, the imperfect looks like this in a real sentence: Yo poseía una casa — "I used to possess a house". Learn the imperfect forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Future

Use the future for plans, predictions and promises, often with mañana, el año que viene or pronto. It talks about what will happen, not what is happening now. For poseer, the future looks like this in a real sentence: Yo poseeré mucho dinero — "I will possess a lot of money". Learn the future forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Conditional

Use the conditional for polite requests, hypotheticals and what would happen, often in si clauses. It softens a request and describes imagined situations. For poseer, the conditional looks like this in a real sentence: Yo poseería un coche nuevo — "I would possess a new car". Learn the conditional forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Present perfect

Use the present perfect for recent actions and experiences, often with hoy, esta semana or ya. It connects the past with the present moment. For poseer, the present perfect looks like this in a real sentence: Yo he poseído una casa — "I have possessed a house". Learn the present perfect forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense. Note the accent on the past participle: poseído — the í carries a written accent because the stem ends in a vowel. Every perfect tense uses poseído after haber.

Pluperfect

Use the pluperfect when one past action happened before another past action. It is the past of the past, and it usually appears with antes de or ya. For poseer, the pluperfect looks like this in a real sentence: Yo había poseído mucho dinero — "I had possessed a lot of money". Learn the pluperfect forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Future perfect

Use the future perfect for something that will already be finished by a future time, often with para mañana or para el viernes. For poseer, the future perfect looks like this in a real sentence: Yo habré poseído un coche nuevo — "I will have possessed a new car". Learn the future perfect forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense. Note the accent on the past participle: poseído — the í carries a written accent because the stem ends in a vowel. Every perfect tense uses poseído after haber.

Conditional perfect

Use the conditional perfect for what would have happened under different conditions. It looks back at a past that never happened. For poseer, the conditional perfect looks like this in a real sentence: Yo habría poseído una casa — "I would have possessed a house". Learn the conditional perfect forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense. Note the accent on the past participle: poseído — the í carries a written accent because the stem ends in a vowel. Every perfect tense uses poseído after haber.

Present subjunctive

Use the present subjunctive after expressions of wish, doubt, emotion and hope, such as espero que or quiero que. The subjunctive does not state a fact; it states an attitude towards the action. For poseer, the present subjunctive looks like this in a real sentence: Espero que él posea mucho dinero — "I hope he possesses a lot of money". Learn the present subjunctive forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Imperfect subjunctive (-ra)

Use the imperfect subjunctive after past wishes and in si clauses about the past, and note the -ra forms shown here; the -se forms use the same stem. For poseer, the imperfect subjunctive (-ra) looks like this in a real sentence: Si yo poseyera un coche nuevo, todo cambiaría — "If I possessed a new car, everything would change". Learn the imperfect subjunctive (-ra) forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Imperative (affirmative)

Use the affirmative imperative for direct commands, instructions and invitations. It tells someone to do something, and it has no yo form. For poseer, the imperative (affirmative) looks like this in a real sentence: Posea una casa — "Let him possess a house". Learn the imperative (affirmative) forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Imperative (negative)

Use the negative imperative, always with no, to tell someone not to do something. It uses the subjunctive forms, so it looks different from the affirmative commands. For poseer, the imperative (negative) looks like this in a real sentence: No poseas mucho dinero — "Don't possess a lot of money". Learn the imperative (negative) forms in the table above alongside this example, and notice how the ending, not the stem, usually carries the meaning of the tense.

Common mistakes

  1. Wrong: Ellos posee una casa — Right: Ellos poseen una casa — Ellos needs the ellos form poseen. The singular posee belongs with él, ella or a singular noun.
  2. Wrong: Ayer, yo poseo — Right: Ayer, yo poseí — The present tense cannot describe a finished action yesterday. Ayer forces the preterite, so the form must change to poseí.
  3. Wrong: De niño, yo poseí todos los días. — Right: Todos los días, yo poseía — For a repeated habit in the past, use the imperfect (poseía), not the preterite. The preterite (poseí) is for one finished action.
  4. Wrong: Yo soy poseído mucho dinero. — Right: Yo he poseído mucho dinero. — Spanish perfect tenses use haber, not ser: he poseído, has poseído, ha poseído. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: Espero que él posee una casa. — Right: Espero que él posea una casa. — After espero que, Spanish needs the subjunctive: posea. The indicative posee is wrong here.
