Questions & Answers about Chujio kiko jikoni.
Swahili marks location with a verb that agrees with the noun class. Chujio is treated as a class 7 noun (ki-/vi-). The class-7 subject marker is ki-, and when combined with the locative root -ko, you get kiko.
- Class 7 singular: kiko
- Class 7 plural: viko
By contrast, iko (i- + -ko) agrees with class 9/10 nouns, not with class 7.
Learners usually treat chujio as a class 7 noun for “instrument” nouns, with the more explicit variant kichujio also common. Its plural is vichujio, and it triggers class-7 agreement:
- Singular: (ki)chujio → kiko
- Plural: vichujio → viko
Both chujio and kichujio are used; if you use chujio, people still typically make the plural vichujio and use kiko/viko for location.
