the.com/forest canopy

means The upper layer of a forest formed by the crowns and interlocking branches of the tallest trees, which filters light, shelters wildlife, and shapes the climate below it.

from 'Canopy' traces back through French to Latin 'canopeum,' meaning a couch or bed draped with mosquito netting — itself borrowed from Greek 'konopeion,' a bed-net named for 'konops,' the gnat it kept out. The word spent centuries meaning fabric overhead — a bed's covering, a ceremonial awning held over royalty — before naturalists in more recent centuries lifted it into the forest, seeing in the interlaced branches overhead the same draped, shielding shape. So the word for 'what keeps bugs off your bed' became the word for 'the roof the whole forest sleeps under' — a fittingly circular bit of history.
