Querer que is always followed by El Subjuntivo (present subjunctive)

Hola Brandon,

I am a little confused too :))

What you are saying in Spanish: quiero que coma and querer comer don't correspond with the English:

"I want to eat" and "I want that I could eat". 

If you mean the difference between "I want to eat" and "I want you to eat", this would be:

Quiero comer (I want to eat) 

Quiero que comas (I want you to eat)

The second one using que + subjunctive because it is two different subjects.

Saludos,

Inma
