Feminine forms of "mīles" and "eques"

[Callaina]

Ah -- I had just checked the entry under puer, thinking that any odd variants would be listed there. But apparently it's more common than I thought, enough so to merit an entry of its own, even.

I wasn't trying to be critical, just engaging in playful speculation

Either way, I guess it's a good thing to mention exceptions. There must be other pairs like puer/puera, though I can't think of any other noun like that at the moment (I can only think of the adjective liber/libera/liberum).

There's adulter/adultera but it's basically an adjective that can be used as a noun.

Logically, by this, the feminine equivalent of puer should be pura.

It would logically be puera, no?

Like ME "girl", come to think of it: https://www.etymonline.com/word/girl

And it lives on in the German word Gör!

Not according to the rule as I stated it (replace -er with -ra). That was the point.

Hm, I'm not sure about that, actually. The OLD has different entries for adulter and adultera as nouns and for adulter, a, um as an adjective — so did it start off as an adjective or a noun?

There's adulter/adultera but it's basically an adjective that can be used as a noun.

Adulter adultera is interesting because it's literally ad-ulter, but ulter has the feminine and neuter forms ultra ultrum.

Along the same lines there's dexter dextera/dextra dexterum/dextrum, and the -fer/-ger adjectives in general (stēlliger stēlligera stēlligerum). At a stretch into Old Latin you could make superus/super supera superum count --super is basically just pre-Classical though.
