🌱 Where it comes from

The word's origin is quite transparent, combining two Latin roots that entered English through French. It joins "counter-", from the Latin "contra" meaning "against", with "act", from the Latin "agere" meaning "to do" or "to act". So, to counteract is, quite literally, to act against something.
