Etymology: "Counteragents" is the plural of "counteragent," a compound of "counter-" and "agent." The prefix "counter-" comes from Old French "contre," meaning "against" or "opposite," which itself descends from Latin "contra" with the same sense. "Agent" comes from Latin "agens," the present participle of "agere," meaning "to do" or "to drive," so an agent is literally something that acts. Put together, a counteragent is something that acts against another thing. The word is a transparent formation: its parts tell you its meaning directly, with no surprising shift from the original sense. In practice it is used of substances that neutralize harmful effects, such as an antidote that reverses a poison or a drug that blocks the action of another.

Synonyms: antidotes, opponents
