Will not is a future tense?

"Will not" is not a future tense by itself; rather, it is a contraction of "will" and "not," used to indicate negation in the future tense. The phrase "will not" indicates that something is not going to happen or is being denied in the future. For example, in the sentence "I will not attend the meeting," the future tense is conveyed by "will," while "not" negates that action.
