Gravida isn't a noun - it's an adjective pushed into use as a noun, probably by nurses :) Doctors who were using it, I'd expect, knew enough Latin to know an adjective when they hear one.

Alas, schooling has changed and Latin is rarely taught any more. Young doctors these days r mr lkly 2 uz phnetk txt msg spch.

So what about "genetalian", then? That's a 24-karat noun.

FWIW, why does it matter? English also lacks the French concept of gender, various case structures seen in Latinate languages, etc etc... you're saying that English seems to use adjectives more than nouns to describe human conditions than other languages and that English is ambiguous because so many words depend on context. But in practice it simply give you an opportunity to craft expressive sentences by manipulating context. Altering a single word can convey frostiness, friendliness, irony, amusement, sarcasm... all by selective management of context. I can see why that might be daunting coming from other languages but once you get the hang it it, it can be good fun. As you know very well. ;-)

BTW, another word missing: ozdraviti. Could be directly translated as "behealthen", i.e. come healthy. Nearest existing expression would be "get well".

Right. How inefficient of English to use a 2-syllable construct instead of a 4-syllable single word. ;-)

Is there a single word for the heavily loaded, 3-syllable English phrase "break a leg"? ;-)
