means The fact or feeling of no longer having something or someone you once had, whether through death, defeat, or simple misplacement.

from From Old English 'los,' meaning destruction or ruin, tied to the verb 'lose' and its Old English ancestor 'losian' (to perish, to be destroyed). The whole family traces back to a Proto-Germanic root suggesting loosening or letting go — possibly a cousin of the same root behind 'loose' and 'dissolve.' So at its core, loss is a thing coming undone: a grip that slackens until what you held slips through.
