Etymology: The word "intersection" passed into English from Middle French, which had taken it from Latin "intersectio," a noun built from "intersecare," meaning to cut between or cut across. The Latin verb combined "inter," between, with "secare," to cut, so the core picture is two lines cutting through each other. That literal sense of cutting is still visible in the English word's form: "intersect" is the verb, and "-ion" is the suffix that turns an action into a noun, so an intersection is literally the act of cutting across, before it came to mean the place where the cutting happens. The shift from act to location is the part that makes the word feel modern. A road junction is a spot where routes cross, and English speakers came to name that spot with the same word that once named the crossing motion itself. The same pattern appears in other "-ion" nouns, but here the physical place has largely displaced the abstract action in everyday use.
