Absent words - K

What is this?
Occasionally I had to translate from Serbian to English, and hit my head against several walls, as it happens to any translator. One of these walls were the words which are absolutely missing in English. In several cases I actually asked Anglophones for help, but didn't get much.
The missing Serbian words are described to the best of my ability. The attempts often proved futile.

The word I can't translate
Description of a possible translation
kajmak
Thing is regional - see kajmak on Wikipedia. There's no word in English.
kakav
what kind of, like what, what like. As in "what's that smell", where "it's a smell" is not the expected answer.
"whuch" is the missing word in english, the proper question to which "such" is the answer.
kasniti
be late - but that's an adjective, it's a property; "kasniti" is a verb denoting an action. Besides, being late is often used for the dead, the difference being only in the article: "the late postman" is a deceased postman, "the postman is late" is what he's doing, running behind schedule
run late - almost there, except that it should apply to things which can't possibly be running
be behind schedule - same misgivings as for "be late", plus the number of things/events which may kasniti is larger than the number of those which have schedules
klas
ear - it's a no go, ear is a part of a mammal's head, while "klas" is exactly the seed-bearing part of a cereal
kod ~
at ~'s house - doesn't really cut it, because you can go "kod ~" even if he's standing in the middle of an empty field. Even if house is omitted, "at ~'s" doesn't work for many situations when something is "kod ~" and there's nothing to attach the 's to - "seo je kod Pere" - he sat at Pera's - Pera's what? Rock on the beach?
with ~ - actually quite wrong, because you can go "kod ~" on your own; that's why "thanks for shopping with us" sounds wrong to me - I'm shopping without any assistance or accompaniment
komad
as an unit of measure, when selling apiece. I've seen larger fruit priced "3$ each" - well, give me four eaches of these, please. In serbian, it's "4 komada".
kuda
"where to" as a single word.
kupač
a person bathing
in sea, river, lake, not in a bathroom
swimmer
is actually wrong, a kupač may not be a swimmer at all
kurac
dick
nope, that's a nickname from Richard
johnson
nope, that's a surname
member
sorry, the genitals are neither a club nor a church nor a political party, despite appearances
penis
that's latin, I'm looking for an english word
prick
a tiny stab? Let's get serious.
wang
is a chinese surname, not an english word
shlong
that's yiddish, looking for an english word
cock
is a rooster, not a reproductive organ
kvar
A malfunction which wasn't there before. An artifact can malfunction from the beginning, but that's not a kvar; it has to have functioned fine first and then to "pokvariti se" (see below) to develop a kvar.
kvašenica
bread fried in a batter, but the batter is just beaten eggs, so it isn't "breaded bread", it's more like "egged bread"
kvočka
setting hen - but only of the chicken persuasion, not of any other bird.
