Is mkutanoni simply the noun? Is there some sort of declension going on that indicates movement toward something?
putting -ni on the end of a noun makes is locative. For example, to say "on the table" (table=meza) you could say "mezani." -ni could mean "at," "in," "on," etc.
Locatives are taught later - about 20 more lessons later. It would be nice to have explanations before the examples
