词源

From Middle English cave, borrowed from Old French cave, from Latin cava (“cavity”), from cavus (“hollow”). Cognate with Tocharian B kor (“throat”), Albanian cup (“odd, uneven”), Ancient Greek κύαρ (kúar, “eye of needle, earhole”), Old Armenian սոր (sor, “hole”), Sanskrit शून्य (śūnya, “empty, barren, zero”). Displaced native Old English sċræf. More at cavum, cavus and cage.
