Why can’t I name my Pokemon Mona?

Question

So in Pokemon Sword I was trying to name an Emolga Mona, but it doesn’t allow it??? Why? If I tried spacing out the letters it doesn’t work. Why can’t I name my Emolga Mona?! It doesn’t make sense!

I'm thinking because it's an anagram for moan

I don't think there's an answer for this (that anyone outside of TPC knows) atm

Answer 1

Is Mona a bad word?
In certain Italian dialects, “mona” is a crude word for a woman's genitals, or an insult along the lines of “stupid.” It's also Spanish for a female monkey.

that's probably why.

I think the Spanish is unlikely to have been the intent, but the Italian one has a plausible reason, if obscure. A monkey seems unlikely to me to be a problematic name.
