Q

The Past Subjunctive

A

El pretérito imperfecto del subjunctivo of all verbs is formed by dropping the -ron ending from the ustedes/ellos/ellas form of the preterite and adding the past subjunctive endings (ra, ras, ra, ramos, rais, ran)
- Verbs that have stem changes or irregularities in the ustedes/ellos/ellas form of the preterite have those same irregularities in all forms of the past subjunctive
*pedir –> pidieron –> pidiera, pidieras, etc
* sentir –> sintieron –> sintiera, sintieras, etc
* dormir –> durmieron –> durmiera, etc
* influir –> influyeron –> influyera, etc
* saber, –> supieron –> supiera, etc
*ir/ser –> fueron –> fuera, etc
(In spain and other parts of the spanish-speaking world, the past subjunctive is also used with an alternate set of endings (-se, -ses, -se, -semos, -seis, -sen)
Use the past subjunctive: required in the same context as the present subjunctive, except that the point of reference is the past. When the verb in the main clause is in the past, the verb in the subordinate clause is in the past subjunctive.
- The expression, “como si” (as if) is always followed by the past subjunctive
- the past subjunctive is commonly ued with querer to make polite requests, to express wishes, or to soften statements

Q

El preterito perfecto

A

(present perfect tense) - expresses what hass happened - refers to recently completed actions or to a past that still bears relevance to the present
:Form the present perfect with the present tense of the verb haber and a past participle. Regular past participles are formed by adding -ado to the stem of -ar verbs and -ido to the stem of -er and -ir verbs
To express something that has just happened, use acabar de + (infinitive), not the present perfect

  • When the stem of an -er or -ir verb ends in a,e, or o, the past participle requires a written accent (ído) to maintain the correct stress. No accent mark is needed for stems ending in u
    ex: ca-er –> caído
    le-er –> leído
    o-ír –> oído
    construir –> construido

Verbs with irregular past participles
1. abrir–> abierto
2. cubrir –> cubierto
3. decir –> dicho
4. descubrir –> descubierto
5. escribir –> escrito
6. hacer –> hecho
7. morir –> muerto
8. poner –> puesto
9. resolver –> resuelto
10. romper –> roto
11. ver –> visto
12. volver –> vuelto

*in the present perfect, pronouns and the word “no” precede the verb haber
