advocate
This word carries a strong sense of public commitment and vocal support. It is not a quiet preference but an active, outward expression of belief intended to influence others or change a system. It is frequently used in legal, political, and social justice contexts where a power imbalance exists. While similar to support, advocacy implies a strategic effort to persuade. A person who advocates is often acting as a voice for those who cannot speak for themselves, blending the roles of a champion and a representative.
Referring to individual people who champion a cause, such as having three advocates on a committee.
Meanings
