> The word "plus" itself is also irregular. Its masculine or feminine nominative plural is "plures", and its neuter nominative plural is "plura".

What's irregular about that?

[nerdponx]

Well, nothing technically, from what Latin I remember. I meant it in the not-technical sense that the nominative form is different from the word stem and it looks superficially like a standard 1st/2nd declension adjective.
