formal written work on a subject

A long, serious book or written work that explains one subject in a very careful and detailed way.

Usage pattern: a treatise on [subject]
Common mistake:
Learners sometimes confuse "treatise" with "treaty" (an agreement between countries) or with "treat" (a verb or a nice thing, like a piece of candy). Another mistake is using "treatise" for any simple article or short essay; in modern use, a treatise is usually long, formal, and detailed.
Synonyms
monograph (A technical term, mainly in academic contexts, for a detailed written study on a single subject.) | discourse (Can refer to a serious written or spoken discussion; slightly broader and sometimes more abstract than a treatise.) | study (Less formal-sounding; can be shorter and not necessarily as systematically organized as a treatise.) | essay (Usually shorter and often less exhaustive or less strictly structured than a treatise.)
Antonyms
summary (Opposite in that a summary gives only the main points briefly, while a treatise explains a subject at great length and in detail.)
Collocations
