Etymology: The verb "intersect" is built from two Latin pieces that both carry a physical sense of cutting. "Inter" meant "between," and "secare" meant "to cut," so the Latin verb "intersecare" literally meant "to cut between" or "cut off." The idea was concrete and almost surgical: one thing slicing through another, dividing it at the point where they meet. English took the word directly from Latin, so the sense of cutting-through stayed at its core. Over time the image shifted from a blade passing through a solid object to two lines or paths meeting and crossing. That abstract, geometric sense of two things overlapping at a point is what the modern verb mostly means, even though the Latin root still describes a cut.
