Where does “cam” come from?
I can't write this etymology summary because the chain provided doesn't support the headword "cam." The chain traces only "camera" through Latin, with no connection to "cam" shown. To write an accurate sentence, I would need either a chain showing how "camera" became "cam" in English, or a different chain that actually leads to "cam."
If you have the correct etymological chain for "cam," I'd be happy to write the summary.
