In a way that cannot be destroyed or forgotten; lasting forever.

Imperishably → It is formed from "im-" (meaning not) and "perish" (from Latin "perire", meaning to die or to be destroyed) and the suffix "-able" (meaning capable of). The word "imperishably" means in a manner that is not capable of being destroyed or dying.
Think of 'not' ('im-') being able to 'die' ('perish') — that's why imperishably means something that cannot be destroyed.
