I was recently wondering where the word `kernel' comes from in mathematics. I am sure the internet must know. I did manage to find
which contains the origin of many math words but it doesn't have `kernel'; it also only seems to address math words you might run into in at most a 1st or 2nd year college math course. I'm wondering if anyone is aware of a reference that might address the origin of more modern math words (but not so modern that it doesn't discuss kernel).
EDIT: By `math etymology' I mean why a particular word was used for a certain math concept. Of course such an explanation might involve discussing the actual etymology of the word.
