The word "full" refers to a state of being filled to capacity or the maximum amount. It describes something that contains as much as it can hold and is often used in various contexts, such as describing a container filled with liquid, a plate of food, or even an emotional state of completeness.
The word "full" comes from Old English "full," which is derived from Proto-Germanic "*fullaz" and is related to the Dutch "vol" and German "voll." Its usage has evolved over time but retains the core meaning of being filled or complete.
