in-demand

The compound adjective "in-demand" is a relatively modern formation, emerging in the 20th century from the common English prepositional phrase "in demand." The preposition "in," from Old English "in," signifies a state of being. The noun "demand" entered English via Anglo-French in the 13th century, tracing back to the Latin "demandare" (de- 'thoroughly' + mandare 'to entrust, order'). The literal sense of being "in a state of demand" logically evolved from the economic principle where a desired good or service is subject to requests from buyers. This concrete commercial logic was later abstracted to describe any person, skill, or product that is highly sought after and popular in a broader social or professional context.
