Overfill → It is formed from "over-" (meaning excessively or too much) and "fill" (from Old English "fyllan", meaning to make full). The word "overfill" means to fill something excessively or beyond its capacity.
Think of putting in 'too much' ('over-') until something is 'full' ('fill'). This helps you remember that overfill means to fill something beyond its limit.
