Other forms: discussed, discussing, discusses
To discuss is to talk about a topic seriously with other people. Discuss the plan, discuss it later, we need to discuss this.
It implies exchange and some purpose: discussing is not chatting, and discussing a problem is expected to move it forward. It takes a direct object with no preposition — discuss the matter, not discuss about the matter, which is one of the commonest learner errors. Note discussion, discussable; and that discuss comes from a Latin verb meaning to shake apart, which is a fair description.
