Etymology: "Frontliner" is formed by adding the agent suffix "-er" to "frontline," a word for the foremost line of troops or, more broadly, the place where something is most directly confronted. The suffix turns the place into a person who occupies it: a frontliner is someone who stands on the front line. The sense has shifted a long way from the military trench. Its modern meaning, a worker who keeps essential services running and faces the public or danger directly, grew out of the wording used during recent public health emergencies, when nurses, delivery drivers, grocery staff and others were described as being on the front line against a crisis. The term is broader than its military ancestor, applying to anyone exposed on behalf of others rather than to soldiers alone.

Synonyms: frontline worker, first responder, vanguard, pioneer, trailblazer
