What defines a 'tense' in grammar?

A tense in grammar refers specifically to the form of a verb that conveys the time of an action or state of being. It indicates whether an event occurs in the past, present, or future. By modifying the verb, the tense provides essential information about when something happens relative to the speaking moment.

For example, in English, past tense verbs indicate actions that have already taken place (e.g., "walked"), present tense denotes actions happening right now (e.g., "walking"), and future tense signifies actions that will occur (e.g., "will walk"). This temporal context is crucial for clear communication in both written and spoken language, allowing speakers and listeners to understand the timing of events.

The incorrect options do not accurately reflect the definition of tense. While one suggests that it defines a location, another relates to adjectives, and the last one hints at relationship phrases, none of these pertain to the core function of tense, which is solely about the timing of actions expressed through verbs.
