"His parent is a teacher"

Translation: Mzazi wake ni mwalimu

[Frank_Pisaturo]

I appreciate the hover-hint -ake (add agreement). It helps test me on adding the correct class/prefix :)

[LobsangC]

Why 'wake', but not 'lake'?

[AGreatUserName]

Because the noun before it, mzazi is an animate m-wa noun. Lake is used with ji-ma nouns in singular (if inanimate)
