I’ve looked in the Oxford Latin dictionary and online for the Latin
singular meaning to menace in the context that someone is a menace. I
found minae, but in both the dictionary and online, it comes up as
plural. Could minae be both plural and singular?
minae, -arum is plural: it is a socalled tantum plurale, meaning “plural only”. This means that the noun does not have a singular form: it only figures in the plural. Think of words like “Athens” or “scissors” and you’ll see what is meant: these English words are actually in the plural - you can’t say “Athen” or “scissor”…
