trade windn.

Brit.

/ˈtreɪd wɪnd/, U.S.

/ˈtreɪd ˌwɪnd/

Origin: Formed within English, by compounding. Etymons: trade n., wind n.¹

Etymology: < trade n. (compare trade n. I.) + wind n.¹, apparently after to blow trade at trade adv. With sense 3 compare earlier breeze n.² 1.Although the name was originally unconnected with uses of trade with reference to commerce (see trade n. III.), the importance of such winds (especially the constant winds near the equator) to commercial navigation eventually led to these senses being associated.

†1. A wind that blows steadily in the same direction for a long period (as a season), esp. at sea (cf. to blow trade at trade adv.). Also figurative. Obsolete (now only as in senses 2, 3).The term was originally applied to any wind having this character. It soon became associated with the examples best known to sailors, the Indian Ocean monsoons and the tropical easterlies, and as a technical term was eventually restricted to the latter. The assignment of quotations to particular senses is often uncertain.
