Why is it mnaenda and not unaenda in this sentence?
I can be both. Mnaenda is for many while Unaenda is for one. The sentence could use some changes. "Wao wanaenda" They are going. It should be defined somewhere in the same page(of the app) whether its singular or plural.
Shouldn't it be "kuwaona"? "Wa" for the thing you will be seeing, lions?
the object infix is optional, but yes that should work
