来自devise, 用作名词。

device: device: [13] A device is something which has been devised – which, etymologically speaking, amounts to ‘something which has been divided’. For ultimately devise and divide come from the same source. The noun device comes in the first instance from Old French devis ‘division, contrivance’ and latterly (in the 15th century) from Old French devise ‘plan’, both of which were derivatives of the verb deviser ‘divide, devise’ (source of English devise [13]).

This in turn came from Vulgar Latin *dīvisāre, a verb based on the past participial stem of Latin dīvidere, source of English divide. The semantic development by which ‘divide’ passed to ‘contrive’, presumably based on the notion that dividing something up and distributing it needs some planning, happened before the word reached English, and English device has never meant ‘division’.

The sense ‘simple machine’ essentially evolved in the 16th century.
=> devise, divide, individual, widow
device (n.): late 13c., from Old French devis "division, separation, disposition, wish, desire; coat of arms, emblem; last will," from deviser "to divide, distribute" (see devise). Sense of "method by which something is divided" arose in French and led to modern meaning.
