Can someone help me understand "rōvys"? I dont understand why it is both plural and singular for bull but then sometimes for other words like knights it is rōvi. And then for this sentence it is rōvī. I would understand if rōvys was singular, rōvi plural, and rōvī accusative both, like horses but I dont.get it.
Rōvys vandis-Nominative Singular
Rōvi vandis-Accusative Singular
Rōvyz vandissa-Nominative Plural
Rōvī vandissa-Accusative Plural
vandis is the same in nominative and accusative; rōvys is declined normally
