The word "unsluice" has a relatively straightforward etymology. It is derived from the combination of the prefix "un-" which means "not" or "reverse", and the verb "sluice". The verb "sluice" comes from the Middle English word "sluysen", which is rooted in Old French "escluse". The Old French term ultimately traces back to the Late Latin word "exclūsa", meaning "a barrier" or "a lock". So, the word "unsluice" basically means "to undo or reverse the action of sluicing" or "to remove a barrier or open a lock".
