Etymology

The word "jigsaw" originated in the 19th century, combining "jig" (from Middle French giguer, meaning "to dance," referencing the tool's rapid up-and-down motion) and "saw" (Old English sagu, a cutting tool). Initially referring to the mechanical tool, it later metaphorically described the puzzle due to its similar interlocking cutting pattern.
