Organization

Structure of the United Nations organization

An organization or organisation (Commonwealth English; see spelling differences), is an entity—such as a company, or corporation or an institution (formal organization), or an association—comprising one or more people and having a particular purpose.

The word in English is derived from the French organisation, which itself is derived from the medieval Latin organizationem and its root organum was borrowed whole from the Greek word organon, which means tool or instrument, musical instrument, and organ.
