The word "capacity" refers to the maximum amount or volume that something can hold or contain. It can also mean the ability or skill to perform a certain task or function. For example, a container's capacity tells us how much liquid it can hold, while a person's capacity for learning indicates how much information they can absorb.
The word "capacity" comes from the Latin word "capacitas," which means "ability to hold" or "capacity." The root "capere" translates to "to seize" or "to take."
