And yes, if you were talking about the Roman gladiators, the plural would be retiari or retiarii; I'm assuming this would be the same.
I was just wondering if it was considered a technical latin word or if it belonged to the usual vocabulary. I mean, the plural for
gladiator is
gladiatorS, probably because it became some kind of usual word, whereas the latin plural should be
gladiatores. I was wondering if it was the same with
retiarius (
retiariuses?
)
