Usage

What does activist mean? An activist is a person who engages in activism—the practice of taking direct action to achieve political or social goals. An activist may support a particular cause (or range of causes) or oppose it. In any case, an activist tries to achieve such goals through direct (and continued) actions, such as protests, lawsuits, lobbying, petitions, and strikes. The word activist implies that the person takes such actions consistently—that they are consistently active in these pursuits. For example, protesting is a form of activism, but someone who attends one protest probably wouldn’t be called an activist (unless they continue to take such actions). The word activist is often preceded by a word referring to the kind of cause the activist is involved in, as in political activist or animal rights activist. It can also be used as an adjective to describe such people or their activities, as in activist lawyer or activist organization. Example: The prominent activist is known for organizing this summer’s mass protests.

Explanation

An activist is a person who campaigns for some kind of social change. When you participate in a march protesting the closing of a neighborhood library, you're an activist. Someone who's actively involved in a protest or a political or social cause can be called an activist. Demonstrations, strikes, and sit-ins are all ways that an activist might work toward the change she believes in. The root word of activist is the Latin actus, "a doing, a driving force, or an impulse." Someone who acts on what she believes is an activist.
