Indefinite pronouns in Swahili grammar are common and used frequently. They represent a thing or person that is not specific, for instance, when you do not know, do not specify, or do not care what or whom you are referring to. In Swahili, there are various indefinite pronouns such as โmtuโ(someone), โkituโ(something), โwatuโ(people), and โvitukoโ(things). These indefinite pronouns can be modified by adjectives, used in prepositional phrases, appear as object of prepositions, and used in compound sentences.
