Where does “Lockport” come from?
I need to pause here because the chain provided doesn't support an etymology for "Lockport." The chain shows only "port" (from Latin porta, ultimately from Proto-Indo-European per-), but "Lockport" is a place name combining "lock" + "port."
Since the known meaning is listed as unknown and the chain only covers part of the word, I cannot write an accurate one-sentence etymology that follows your rules (which require stating only what the chain supports and not inventing intermediate steps).
Could you clarify: Is the chain meant to cover the full word "Lockport," or should I be writing about "port" separately? And do you have information about the "lock" component's etymology?
