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 tasar, the present indicative looks like this in a real sentence: Yo taso el coche — "I appraise the car". 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 tasar, the preterite looks like this in a real sentence: Yo tasé por un experto — "I appraised by an expert". 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.
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 tasar, the imperfect looks like this in a real sentence: Yo tasaba la casa — "I used to appraise the 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.

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

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.
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 tasar, the pluperfect looks like this in a real sentence: Yo había tasado el coche — "I had appraised the car". 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.

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.
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 tasar, the present subjunctive looks like this in a real sentence: Espero que él tase el coche — "I hope he appraises the car". 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 tasar, the imperfect subjunctive (-ra) looks like this in a real sentence: Si yo tasara por un experto, todo cambiaría — "If I appraised by an expert, 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 tasar, the imperative (affirmative) looks like this in a real sentence: Tase la casa — "Let him appraise the 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 tasar, the imperative (negative) looks like this in a real sentence: No tases el coche — "Don't appraise the car". 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.
Example sentences
Ten natural sentences with tasar, covering different tenses and persons. Each one uses a form from the tables above.
- Yo taso por un experto — "I appraise by an expert"
- Él tasa la casa — "He appraises the house"
- Yo tasé el coche — "I appraised the car"
- Yo tasaba por un experto — "I used to appraise by an expert"

- Espero que él tase la casa — "I hope he appraises the house"
- Yo había tasado el coche — "I had appraised the car"
- Ellos tasaban por un experto — "They used to appraise by an expert"
Common mistakes
- Wrong: Ellos tasa la casa — Right: Ellos tasan la casa — Ellos needs the ellos form tasan. The singular tasa belongs with él, ella or a singular noun.
- Wrong: Ayer, yo taso — Right: Ayer, yo tasé — The present tense cannot describe a finished action yesterday. Ayer forces the preterite, so the form must change to tasé.
- Wrong: De niño, yo tasé todos los días. — Right: Todos los días, yo tasaba — For a repeated habit in the past, use the imperfect (tasaba), not the preterite. The preterite (tasé) is for one finished action.
- Wrong: Yo soy tasado el coche. — Right: Yo he tasado el coche. — Spanish perfect tenses use haber, not ser: he tasado, has tasado, ha tasado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: Espero que él tasa la casa. — Right: Espero que él tase la casa. — After espero que, Spanish needs the subjunctive: tase. The indicative tasa is wrong here.
