I seem to recall our discussing this on the old board, but if not:
I have researched the term “issue” enough to understand its Latin and PIE origin, and how the sense of “flow out” “discharge” came to mean so many things, from “progeny” to being “issued helmet and cartridge belt.”
I am wondering when “issue” took on its psychological sense. Specifically, did the psychology term, e.g., “issues with parents” “issues with conflict” come from the meaning of issue as “matter under discussion”, or did psychologists use take it from the medical sense of a “discharge” but apply it to the subconscious?
If the latter, it really is a wonderfully descriptive metaphor, so I hope that’s the answer.
(Be careful: I have issues with disappointment; however, I won’t make an issue out it.)
