pint

This term functions as both a precise measurement of volume and a common shorthand for the container that holds that volume. In a pub or bar setting, it almost exclusively refers to a glass of beer, where the word describes the vessel rather than the abstract unit of measure. Because it is a standardized unit of capacity, it is used as a count noun when referring to multiple containers or specific quantities (e.g., two pints of milk), but it describes a fixed volume that does not change regardless of the substance contained.
