Subjunctive

Although hard to grasp at first, it is simple.

Basically you take an -ar verb and give it -er/ir endings. And vice versa with -ir/er verbs.

Why?

The subjunctive tense is to express moods, doubt, happiness, and will.

For instance, I always wondered why I am supposed to say "I wish I were on vacation."  "The teacher insists that he speak Spanish."   That is the subjunctive in English, though rare.  In Spanish, however, it is widely used.

"It is important that you be on time."  I doubt that he can come.  Why is that subjunctive? Because if "he can" is uncertain, so you use the subjunctive instead of indicative.  "I want you to clean your room," is not subjunctive in English but in Spanish it usually is. They say "I want that you clean your room."

Formula:  Take the Yo form of the present tense minus -o and add -e, es, e, emos, en for -AR verbs

and er/ir  take the yo form present tense minus -o add -a, as, a, amos, an

Tomar                                                 Vivir

Plus it always has "que"  which means that.

I want that you stay with me. (quedarse)

Quiero que te quedes conmigo.

He hopes that you come with him. (venir)

El espera que vengas consigo.

I want that you do not smoke in my room. (fumar)

Quiero que no fumes en mi cuarto.

I hope (that) you have a great summer and call me! (tener)

Espero que tengas un buen verano y me llames!

I'm sad that you are sick. (estar)

Lo siento que estés enfermo.
