In Swahili grammar, there are several tenses that are used to indicate different time frames of an action or event. The tenses theory in Swahili grammar includes the present tense, past tense, future tense, and the perfect tense.

The present tense in Swahili is used to express actions or events that are happening currently or are generally true. It is formed by adding the appropriate prefixes to the verb stem.

The past tense is used to describe actions or events that have already happened. It is formed by adding the appropriate suffixes to the verb stem.

The future tense is used to express actions or events that will take place in the future. It is formed by adding the appropriate prefixes to the verb stem.

The perfect tense is used to convey actions or events that have been completed in the past. It is formed by using the auxiliary verbs “kuwa” (to be) and “ku-” (to have) in combination with the past participle.

Mastering the tenses theory in Swahili grammar is essential for effective communication and comprehension in the language. By understanding the different tenses, learners can accurately convey the time frames of actions or events.
