The word "source" refers to a place, person, or thing from which something originates or can be obtained. It can signify the starting point of information, materials, or energy. For example, in research, a source might be a book, article, or expert that provides facts or insights.
The word "source" is derived from the Old French word "sourcer," which means to rise, and from the Latin "surgere," meaning to rise up or to spring forth. The development reflects the idea of something emerging or arising from a particular point.
