"The men hear a knight."
Translation:Vali azanti rȳbis.
Azantys and azanti are both singular. Azantyssy and azantii are both plural. The difference between azantys and azanti is case. If you've never learned about grammatical cases, I suggest looking them up on Wikipedia. But basically, it depends on which role the noun has. Azantys/Azantyssy is the nominative case, which means it's used for the subject of a sentence. Azanti/azantii are the accusative forms, which means the word is the direct object of a verb. It's comparable to the English I/me and we/us distinction, which is a remnant from a time when English too had cases.
