Etymology: "Improver" is a straightforward formation: the verb "improve" with the agent suffix "-er," which names someone or something that performs an action. An improver is one who makes progress, and the word's history is essentially the history of that suffix. The suffix itself has a long pedigree. It descends from a Latin ending "-arius," which named a person connected with a trade or activity, and which passed into Old French as "-ier" before English adopted it. Old English had its own native form, "-ere," which settled into the Middle English "-er" that now attaches freely to English verbs. "Improve" is the older element of the pair. It came into English from Anglo-Norman "emprouer," itself rooted in Old French and ultimately in Latin, and its original sense was closer to "make profitable" than to the general "make better" of modern use. The agent noun built on it follows the same logic: "improver" describes whoever brings about that change.
