A logo (abbreviation of logotype, from Greek: λόγος logos "word" and τύπος typos "imprint") is a graphic mark, emblem, or symbol commonly used by commercial enterprises, organizations and even individuals to aid and promote instant public recognition. Logos are either purely graphic (symbols/icons) or are composed of the name of the organization (a logotype or wordmark). In the days of hot metal typesetting, a logotype was one word cast as a single piece of type, e.g. "The" in ATF Garamond (as opposed to a ligature, which is two or more letters joined, but not forming a word). By extension, the term was also used for a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage, a company's logo is today often synonymous with its trademark or brand.
