A tense system is a grammatical system that indicates when an action or state occurs in time (past, present, future). It's how languages mark time. English has a relatively complex tense system with simple, continuous, perfect, and perfect continuous forms. Different languages organize time differently. Some languages focus more on aspect (how an action unfolds) than on tense. Understanding the tense system is crucial for accurate communication. Think of it as the timeline of a language.
