How to Use Negative Tenses in Clauses

In Swahili, a negative tense applies to all the tenses as opposed to having different ones in ordinary clauses. The suffix is yay and it means the person who remains. And so it almost becomes like a relative verb, or it's like a marker on the verb that says this verb only applies to the previous noun. There are more complex examples such as wagini, watakau pika, geisho, watak winda, zanzibat.
