Prepositions of Time in Swahili grammar, known as Viunganishi vya Wakati, are used to indicate a particular period, whether it’s specific or general, in which something happens. They are crucial in enhancing fluent communication, enabling the understanding of different temporal relations. These prepositions can provide information about when an event occurred, such as in the past, present, or future. Excellent knowledge and usage of these prepositions, therefore, contribute to better comprehension in Swahili.
