Questions & Answers about Kiwanda kiko mjini.
Kiko shows that something is located somewhere.
In this sentence:
- kiwanda = factory
- kiko = it is there / it is located
- mjini = in town / in the city
So kiko is not just a random verb form. It is a location form that agrees with kiwanda.
Because kiwanda belongs to the ki-/vi- noun class, the sentence uses ki- in kiko.
Because ni and kiko do different jobs.
- ni is usually used for identifying or equating things:
- Huyu ni mwalimu = This is a teacher.
- kiko is used for location/existence:
- Kiwanda kiko mjini = The factory is in town.
So Kiwanda ni mjini would sound unnatural for normal location. For saying where something is, kiko is the natural choice.
