Alegrarse

[Larkin]

Does this verb always require the use of the subjunctive?

What prepositions are commonly placed after the following verb conjugations?

Me alegro (When I am the subject)
Me alegra (When I am the indirect object)

Should I just use "de que"? Thanks.

Alegar(se) does not require the subjuctive. The que and de que usage is regional. I think de que is the most correct usage, but it isn't often heard in Latin American Spanish. Wait for native speakers to give you a more definitive answer.

Alegrarse states a personal emotion. It is always followed by 'de'.
If the subject changes, use 'que' to introduce a noun clause. The verb in the noun clause will be conjugated AND the mood will always be subjunctive.
If the subject doesn't change, an infinitive is used (there is no noun clause).

Alegrarle algo a alguien is also stating emotion, therefore, the subjunctive is always used. However, 'de' does not follow the verb.
If the subject changes, use 'que' to introduce a noun clause. The verb in the clause will be in the subjunctive mood.
If the subject doesn't change, an infinitive is used (no clause).

I agree with Rusty, but I think a couple of examples might be useful:

- Me alegra que estés aquí. -> The fact that you are here makes me glad.
- Me alegro de que estés aquí. -> I am glad because you are here.


- Me alegra mucho verte. -> I am seeing you, and that makes me happy. The subject of both verbs is "yo", so the subjunctive must be changed for the infinitive.
- Me alegro mucho de verte. -> I am glad because I am seeing you. Sincé you don't perform the action of seeing, then the second verb is an infinitive.
If you use the infinitive, there is no "que". :)
