Etymology

The term "know-how" emerged in the early 19th century as a compound of "know" (from Old English cnāwan, meaning "to perceive or understand") and "how" (from Old English , meaning "method or manner"). It originally described practical expertise distinct from theoretical knowledge, reflecting industrial and technical advancements where hands-on skill was valued. The word's structure directly mirrors its meaning—combining "know" (understanding) with "how" (method) to emphasize actionable competence.
