"Affiliate" means to officially connect or attach oneself with an organization or company. You can use this when talking about business, organizations, and subsidiaries. Often subsidiaries, a company controlled by another company, is affiliated with a larger company. Ex: Converse is actually an affiliate of Nike. Ex: Lebron James affiliated with Samsung in 2014, but it didn't end well.
