Definition of affiliate

The word "affiliate" has its roots in Latin. In the 14th century, the Latin word "affiliare" meant "to bind or unite" or "to make kin". From this Latin root, the word "affiliate" emerged in Middle English, initially meaning "to join or unite with" or "to connect". In the context of business, the term "affiliate" first appeared in the 16th century, referring to a person or organization joined or connected with another, often in a partnership or alliance. Over time, the meaning expanded to include a more specific type of business relationship, where one entity, usually a company, joins forces with another, often to promote a shared product or service. Today, the word "affiliate" is commonly used in the context of marketing and commerce, referring to a partnership or arrangement where one entity promotes another's products or services, often earning a commission or fee in return.
