Spillable → It is formed from "spill" (from Old English *spillan*, meaning to cause to fall or to let fall) and "-able" (meaning capable of). The word "spillable" means capable of being spilled or able to be poured out.
Think of something that can 'fall' or 'be let fall' ('spill') and is 'capable' of doing so ('-able'). This helps you remember that 'spillable' refers to something that can be spilled.
