So the writers of the
40k universe love to
Call A Rabbit A Smeerp, and while this does add character to the universe, it does make for a lot of new words to learn... A camera is called a pict recorder, a radio is called a vox caster, binoculars are called magnoculars, a surgeon is called a chirurgeon, and so on.
Has anyone ever bothered to prepare a whole glossary of those
40k terms? My issue is not so much to figure out what they mean (you can usually infer from context), but rather the reverse: when writing
40k fiction, I often want to know if there is an in-universe term for something or other.
