Which concept refers to the grammatical relation of words conveying time?

The concept that refers to the grammatical relation of words conveying time is tense. Tense is a crucial aspect of grammar that indicates when an action takes place—whether in the past, present, or future. For example, in English, the verbs "walked," "walk," and "will walk" highlight different times in which the action occurs, demonstrating how tense affects the meaning of a sentence.

Other options do not capture the aspect of time in grammar. Gender refers to the classification of nouns and pronouns as masculine, feminine, or neuter. Number deals with the quantity to which nouns refer, such as singular or plural. Context relates to the surrounding language or situation that helps determine the meaning of words but does not specifically address the grammatical conveyance of time. Hence, tense is the accurate concept that aligns with the temporal aspect of language.
