Treatise

nounPronunciation: /ˈtriː.t̬ɪs/

In Portuguese: Tratado

What does “Treatise” mean?

A formal, systematic, and comprehensive written work dealing methodically with the principles and evidence of a particular philosophical, scientific, or technical subject.

Etymology

From Middle English tretys, from Anglo-Norman tretiz, formed on Old French traitier, 'to deal with, to treat', from Latin tractare. The word came to name extended, systematic written works that treat a subject exhaustively and methodically.

Usage note

A treatise is more formal and exhaustive than an essay, and broader in scope than a monograph, which typically addresses a single narrow topic.

Synonyms
