Etymology: The word "doer" is about as transparent as English gets: it is simply the verb "do" with the agent suffix "-er," meaning one who does. Its ancestor, Old English "dōere," meant "a doer; worker," and it was built the same way, from the verb "dōn" plus the suffix that Old English used to form nouns for people who perform an action. The older sense matters here. In Old English the word leaned toward labour and performance rather than the vague sense of "someone who does things" it carries now. Medieval speakers used it for workers and agents who carried out tasks, so the modern idea of a "doer" as a person of action is close to the original meaning, only broadened over time. The word reached Middle English as "doer," "doar," and "doere," and its spelling wandered across those centuries before settling into the form used today.
