is subjunctive just usinig the present endings but changing the a-e and vice versa?

I came across the endings for the subjunctive and was wondering is it just a-e and e-a as long as you start with the yo form. example Tengo-tenga Espero tengas un dia bien

Hi and welcome to the forum. Here is a flashcard set that might help you.

Answer 2

For present subjunctive that's basically it, plus the irregulars (dar, ir, saber, estar, haber, ser).

Also, some verbs have spelling changes or to maintain the original pronunciation. Most of them are the same as the preterite changes.

e.g. yo busco -> yo busque (busce doesn't maintain that hard consonant)

Lastly, there's stem changes (o->ue, e->ie but not in nos/vos, if it's ir then the o->u and e-> i in the nos/vos) (and if it's e->i it changes in every form)

i understand the stem change as long as it stems in the yo form in present tense and for the busque is it the car gar zar rule like in the preterite? - fuego1995, Apr 26, 2011

Answer 3

You are very close to the general rule-of-thumb.

(1) Start with the yo form

(2) Drop the yo ending.

(3) For -ar verbs add an -e (For -er and -ir verbs, add an -a).

The cool thing for me is the -ar verbs get the -e and the -er/-ir verbs get the -a. (sort of opposite of how you'd think, see?)

(Mind you, we are talking about present subjunctive. Subjunctive is not a tense, but a mood. It has the full range of tenses.)

And, there may be exceptions to this general rule. - webdunce, Apr 25, 2011

Not bad, but I think you would say it more like, "Espero que tengas un buen día"
