Root Explanation

Irreplaceable → It is formed from "in-" (meaning not) and "replace" (from Latin "replacere", meaning to place again) and "-able" (meaning capable of). The word "irreplaceable" means not capable of being placed again or unable to be replaced.

Memory Tip

Think of something that cannot be 'placed again' ('replace') and is 'not' ('in-') capable of being replaced — that's what makes it irreplaceable.
