Etymology

Origin of source

First recorded in 1300–50; Middle English sours (noun), from Old French sors (masculine), sourse, source (feminine), noun use of past participle of sourdre, from Latin surgere “to spring up or forth”; cf. surge

Explanation

The noun source describes an origin, like the source who gave the journalist the information that broke a new story, or the place something originates, like the source of a river, or the Web site that is your source for celebrity gossip. The noun source can also refer to information obtained from documents, such as books, letters, newspapers, and journals. For example, when you write a research paper, you read, paraphrase and quote from sources. A source can also be a place where you get things, like a certain store being your source for discount sneakers or something that provides, like oranges, a good source of Vitamin C.
