Synonym discussion
Sense: noun/1
Defender, protector, guardian, advocate, and champion all describe someone who takes action for another person or a cause. A defender actively fights against threats — whether physical attacks on a place or verbal attacks on an idea. A protector focuses on keeping someone safe from harm, often in a caring or parental way. Guardian suggests a formal or legal duty for another person's well-being. Advocate emphasises speaking or writing in favour of a cause rather than physically shielding it. Champion suggests someone who fights enthusiastically and publicly for a cause. For example, a lawyer is an advocate for a client, a parent is a protector of a child, a legal guardian has court-appointed responsibility, while a defender of free speech might protest and write to protect that right.

Etymology
The word 'defender' entered English in the 1300s from Old French 'defendeor', which came from the Latin verb 'defendere' meaning 'to ward off' or 'to protect'. The original meaning — a person who protects against attack — has remained central for over 700 years. In the 1800s the word was adopted in team sports to describe players whose role is to prevent the opposing side from scoring.
