Where does “touchy” come from?

I appreciate the detailed setup, but I notice there's a critical problem: the etymological chain provided traces "tetchy/tech/technician/technic" back through Latin and Proto-Indo-European, but the headword is "touchy," which doesn't appear in that chain at all. These are completely different etymologies: - **Touchy** derives from "touch" (Old French *tuchier*) - **Tetchy** derives from "tetch" (possibly from "tic" or dialectal origins) I cannot write an accurate summary sentence because the chain doesn't support the headword given. Could you provide: 1. The correct etymological chain for "touchy," or 2. Clarification that the headword should be "tetchy"? I won't fabricate a connection between "touchy" and a "tech-" etymology just to complete the assignment.
