k.m.n.

Hungarian: k.m.n.

Medical abbreviations are always a load of fun; it's difficult to get a good list (there's a great Spanish list, but it's now no longer free).  So as I find them in various translations, I've been trying to run them down more consistently. In Hungarian diagnoses, then, k.m.n. stands for külön megnevezés nélkül, which translates as not otherwise specified, sometimes itself abbreviated to n.o.s. or NOS. Actually, that's common in the various nomenclatures, like the DSM. And it's also used as n.o.s. in the UN Numbers for chemicals.

Aha, here's actually a great list of magyar orvosi rövidítések  - oh, wait, that actually seems to be Hungarian translates of English abbreviations.  This one's more Hungarian.

Cara sencilla/cara doble

Spanish: cara sencilla and cara doble

Single-face and double-face?  What?  But in telecommunications, this is how we talk about simplex and duplex transmissions.
