means The act of removing, selling off, or approving something so it's no longer blocking the way — whether that's unsold inventory, security paperwork, or a plane waiting to land.

from Built from the verb 'clear,' which traces back to Latin 'clarus' meaning bright or evident — the same root behind 'clarity.' Something cleared was made plain or free of obstruction. English bolted on '-ance' to turn the action into a noun around the 1600s, and from there it fanned out: clearing debts, clearing land, clearing customs, and eventually — much later — clearing out the unsold stock nobody wanted at full price.
