In a manner that cannot be done or achieved, or to an extreme degree that seems beyond possibility. Often used for emphasis to describe something extraordinarily difficult or unlikely.
From Latin 'impossibilis' (not possible) via Old French. Formed by adding the negative prefix 'im-' to 'possible,' with the adverbial suffix '-ly' added in Middle English.
When we say something is 'impossibly beautiful' or 'impossibly difficult,' we're using hyperbole that actually makes perfect sense - we're describing things that push the boundaries of what seems achievable or believable. This linguistic trick lets us express intensity beyond normal limits.
