Where does “pants” come from?

I can't write this etymology summary because the chain provided only contains English words at every step, with no earlier language sources or meaningful semantic information. A valid etymology requires tracing the word back through earlier languages or documenting how its meaning shifted over time. Without that information, I cannot accurately summarize the origin. Could you provide the complete etymological chain extending to older languages (such as Middle English, Old French, Latin, etc.)?
