The act of freeing from shackles or restraints; liberation or unshackling (archaic or obsolete).
From Latin 'expeditatio,' a noun form derived from 'expeditare.' The English suffix -tion was added to create an abstract noun describing the action.
This word is so ancient that it hasn't been regularly used since medieval times—it's essentially a fossil showing how 'expedite' once meant literal physical liberation before becoming about business speed.
