Answer 2

First link:

present subjunctive

Except for the irregulars, the general rule as stated there is:

To conjugate a verb in the present subjunctive, you must first remember what the indicative present yo form is. In the present subjunctive, instead of forming a stem from the infinitive, the stem is formed from the yo form of the present indicative.

To the end of this new stem, add the appropriate ending depending on the subject of the verb and infinitive ending of the verb. There are only two ending sets for the present subjunctive; one for -ar verbs and one for both -er and -ir verbs.

Present Subjunctive Endings

-ar verbs -er and -ir verbs yo -e -a tú -es -as usted, él, ella -e -a nosotros -emos -amos vosotros -éis -áis ustedes, ellos, ellas -en -an

Second link:

imperfect subjunctive

Again, except for the irregulars:

To conjugate a verb in the imperfect subjunctive, you must first remember the 3rd person plural of the preterit. Instead of using the infinitive for a stem, the imperfect subjunctive uses the 3rd person plural of the preterit (without the -ron).

1st option 2nd option yo -ra yo -se tú -ras tú -ses usted, él, ella -ra usted, él, ella -se nosotros -ramos nosotros -semos vosotros -rais vosotros -seis ustedes, ellos, ellas -ran ustedes, ellos, ellas -sen
