trajon

Middle Low German trado (track, trail, course) entered English as 'trade' in the 14th century. The original meaning was a path repeatedly walked — the track worn by habitual passage, the route made evident by use. By the 15th century, 'trade' had shifted to mean a course of business, a regular dealing — the same concept applied to commerce: trade was the path of exchange, repeated and established.

The trade routes of the medieval world — the Silk Road, the Amber Road, the Saharan caravan routes — were literally tracks worn into landscapes by generations of merchants. The road to Constantinople was a trade route not because someone designed it but because thousands of traders walking the same direction over centuries had worn a path visible from above. The word captured exactly this: commerce as repetition, exchange as the accumulated pressure of habitual passage.

The British trade associations — trade guilds, trade unions, trades people — reflected the word's shift to mean a specific occupation. A trade was what you did repeatedly, the path of your livelihood. The trade wind, which mariners named by the 15th century, blew steadily in the same direction, allowing reliable passage — the same word applied to reliable, repeated atmospheric movement.

The Transatlantic trade — including the slave trade — used the same vocabulary as the spice trade: 'the trade,' 'trading posts,' 'trade goods.' The word's neutrality absorbed atrocities: the same term covered cloth and human beings. Language does this. The path worn into the ground by habitual passage carries whatever the travelers choose to bring.
