The term offshore refers to something that is situated away from the mainland, typically in the context of operations, businesses, or activities that take place in the sea or ocean. In business, it often describes companies that are based in another country, often to take advantage of tax benefits or lower regulations.
The word "offshore" is derived from the combination of "off" and "shore." The term began to appear in the late 19th century, combining the notions of being away from the land or shore, particularly relating to the sea.
