Root Breakdown
Root-derivedre- (in) + -cept- ("taken") + -or (thing that does) = "the thing that takes in." Built on the Latin -cept- stem rather than -ceive, receptor is the body's molecular catcher: a receptor sits on a cell and grabs the specific molecule meant for it, the way a lock receives only its key. Compare receiver, the same idea in everyday (non-biological) life.
