Etymology

The word "cocoon" entered English in the 17th century from French cocon, derived from coque (meaning "shell" or "husk"), which itself traces back to Latin coccum (a berry or grain). The French diminutive suffix -on gives the sense of a small protective shell. The term originally described the silky casing spun by insect larvae, later metaphorically extended to any protective enclosure.
