What does supply mean?
Supply means both a stock of something and the act of making something available. A noun use might refer to a country's food supply, a room's supply of paper, or the amount of a product available in a market. As a verb, supply describes providing goods, information, or assistance: a charity may supply food and clothing, while a witness may supply crucial details. The word often conveys reliability or sustained availability rather than a single casual act of giving. In economics, supply is one half of the familiar relationship between supply and demand, describing the quantity of a good or service available to buyers. Because the word appears in both ordinary and specialized contexts, it is especially useful for discussing resources, practical needs, and the systems that keep people or organizations equipped.
A stock or quantity of something available for use or distribution; also, the action or process of making something available.

Supply entered Middle English through Old French, ultimately drawing on the Latin verb supplere, meaning “to fill up” or “supply.” The Latin root also produced words such as supplement and supplementary, which share the idea of adding to something so that it becomes sufficient. Over time, English supply came to emphasize making goods or resources available to others.
