Origin and history of cave

1540s, "secret storehouse, treasure chamber; case for valuables," from French cabinet "small room" (16c.), diminutive of Old French cabane "cabin" (see cabin); perhaps influenced by (or from) Italian gabbinetto, diminutive of gabbia, from Latin cavea "stall, stoop, cage, den for animals" (see cave (n.)).

The meaning "case for safe-keeping" (of papers, liquor, etc.) is from 1540s, gradually shading to mean a piece of furniture that does this. The sense of "private room where advisers meet" (c. 1600) led to the modern political meaning "an executive council" (1640s); perhaps originally short for cabinet council (1620s); compare board (n.1) in its evolution from place where some group meets to the word for the meeting group. From 1670s also "building or part of a building set aside for the conservation and study of natural specimens, art, antiquities, etc."

"box-like receptacle or enclosure, with open spaces, made of wires, reeds, etc.," typically for confining domesticated birds or wild beasts, c. 1200, from Old French cage "cage, prison; retreat, hideout" (12c.), from Latin cavea "hollow place, enclosure for animals, coop, hive, stall, dungeon, spectators' seats in the theater" (source also of Italian gabbia "basket for fowls, coop;" see cave (n.)). From c. 1300 in English as "a cage for prisoners, jail, prison, a cell."
