Etymology: The word "treatise" carries a sense of formal, systematic authority today, but its root meaning is much plainer: it comes from the verb "treat" in its old sense of discussing or handling a matter. Middle English "tretys" passed into English from Anglo-Norman "tretiz" and Old French "traitis", a noun meaning an account or a treatment of a subject, which grew out of "traitier", to deal with or treat. So a treatise was originally just an account of something, the product of someone handling a topic at length. Over time the word narrowed. What began as any discussion or report came to mean a work that gathers a subject together in orderly detail, with the writer's own evaluation running through it. The "treat" in the word is the same verb that gives us "treaty" and "treatment", all of them tracing back to the idea of working over a matter, and the link is still visible when a treatise is said to "treat" its subject.
