Questions & Answers about Me enoja que él no apoye el proyecto.
Why is the verb apoyar in the subjunctive form (apoye) instead of the normal present tense (apoya)?
In Spanish, when you express an emotion or feeling about someone else's action, that action takes the subjunctive. Here, Me enoja que (It angers me that) is the emotional trigger. Because the subject changes from you (the person feeling the anger) to him (él), you must use the subjunctive apoye.
Why do we say Me enoja instead of something like Yo estoy enojado?
Verbs of emotion often work just like gustar. Me enoja literally means "It angers me." The entire idea after the word que (that he doesn't support the project) acts as the "it" that is causing the anger. You could say Estoy enojado de que..., but Me enoja que... is a very natural, concise way to express this.
Why use apoyar for "to support"? Shouldn't it be soportar?
This is a classic "false friend." In Spanish, soportar usually means to tolerate or to put up with something (like enduring an annoying situation or bearing a physical weight). When you mean "to support" in the sense of backing an idea, a project, or a person, you always use apoyar.
Is it strictly necessary to include the pronoun él here?
