'Ya' and 'Za'
When should you use 'ya' and when should you use 'za'? I'm confused...
It is explained in the tips and notes. Make sure you are reading those. It is explained bit-by-bit as you progress through the tree.
I am, but I don't understand the tips & notes, so this is what the discussions are for. If you don't have anything helpful to say, don't say anything.
I'm sorry, I am trying to be helpful. Being rude doesn't help either. Try looking at the Wikipedia article for the language: https://en.wikipedia.org/wiki/Swahili_language#Agreement It has a chart listing the "-a" preposition for every noun class. Basically it works just like an adjective, where it has to agree with a particular noun class. So "ya" is used with several different classes of nouns, while "za" indicates the plural of the "N/N" class that doesn't inflect the noun itself, or the plural of the "U/N" class.
