What is a subjunctive verb?
I went to look up comer and conjugate it in the past and future tense but it said subjunctive and nothing about past tenses. It was confusing.
The subjunctive is one of 3 moods in Spanish. It is used to express abstractions and more. If you click on the More tab at the top and go to Spanish grammar there is a good article on the mood there. Welcome to the forum.
