You confused me too, first time I read it. What's wrong with tadpoles being called polliwogs, frexample[1], is someone just feeling a bit over-PC? (Actually, the sound of the P-name likely inspired the form of the G-name, which
is, very much arguably, not something to be said due to the luggage it has built up since is was coined sometime in the 1800s. If it was the American childrens-fiction inspiration for the name, as opposed to the British-in-Egypt possible source for the G-name, which might well have come with some Imperialistic luggage already in existence upon its conception.)
Anyway (now having derived what you really meant), as others have said (in fewer words than me) if you can find their entries in the Raws then you can add in the relevent [SELECT_CASTE:{FE}MALE] lines and naming them yourself, in addition to the [GENERAL_CHILD_NAME:x:xs] one. (Not that I've modded much, but I assume that by putting a different [GCN] within each [SC] you could have their children's names gender-specific, also. Right? If you had something you could put there. (See foal/filly info somewhere in the midst of one of the footnotes I've written, though.))
[1] Though I wasn't aware that frogs were in the game[2][3] . A quick search through the raws shows that there are
words for them, and in the description of Amphibian Men. So they exist as a
concept.
[2] Except as vermin? If they're that, then tadpoles/polliwogs would necessarily have to be a separate, aquatic-only vermin. If that's possible.
[3] Swans are also absent (so no cygnets). Tigers and Leopards (not to mention Lions/Cougers/Panthers/etc and their respective "-esses") could be differentiated as suggested, I suppose, as could female dogs (as opposed to male "dog dogs"?), female foxes (opposite "dog foxes" or "reynards"?). Colt (and filly) would have to refer to male (or female) horses between 1 and 4 years old, and I'm not sure the mechanisms are in place to do for animal children what can be done for dwarf children (after "baby", before
adult peasant grower). But before that, IRL, they are foals, after that, they are stallions(/mares). Fawns already exist (if you mean young deer). I don't recognise "Aria" as being anything animalistic[5], and "Neonate" I thought referred to Human (+dwarf?) babes of less than a month of age, and again I can't see that mechanism existing without a re-write. Cria is a young Llama, IIRC, BICBW. Jack[asse]s need to be partnered with Jennies. Anyway, I seem to recall someone released some modified raws with
all creatures given their gender[3]-specific names, a while ago. Perhaps for easy identification on screens where the gender symbol wasn't obvious. Or just for flavour.
[4] Which I feel is more accurate than the subject title. Although there's the old phrase of "Gender is what's between your ears, sex is what's between your legs, sexuality is
who's between your legs," which would clearly not support this correction if we didn't have a clearcut gameworld without such dislocations from the oft-expected norms, perfect fidelity, apparently foolproof (and anti-spore) birth control by all unmarried female sentients, etc.
[5] Aria... Female version of an Aries The Ram? Maybe a particularly wild variety of sheep where "Ewe" just didn't cut the dash?
