means The act of exchanging one thing for another — goods, currencies, or securities — usually in pursuit of a profit on the difference.

from Trade traces back to Middle Low German 'trade,' meaning a track or course — literally the path one walks. The word drifted into English via trade routes, keeping that sense of a well-worn path between people, before narrowing to mean the commerce that happened along it. By the time 'trading' emerged as its active form, the walking had turned into dealing — but the root idea, a path worn smooth by repeated passage, still underwrites every transaction.
