When you give your active support to an idea or cause, you are showing your advocacy for that cause. Your advocacy for an animal rights group might help raise money to save stray pups.

The noun advocacy comes to English from a term used in Roman law. An advocate was a professional whose job was to plead cases in front of a court of law. That meaning led to the verb form advocate, as well as advocacy, to describe the work of an advocate. "The lunchroom staff were advocates for healthier school lunches; their advocacy was supported by parents and the school board; however, the students were reluctant to give up their cookies and chips."
