The word "support" refers to the act of providing assistance, help, or reinforcement to someone or something. It can imply emotional backing, physical aid, or even financial assistance. In general, support means standing by someone or something and providing the necessary resources or encouragement they need to succeed or cope.
The word "support" originates from the Middle English term "supporten," which comes from the Old French "supporter," derived from Latin "supportare" where "sub-" means "under" and "portare" means "to carry." Thus, it literally means to carry from below.
