A scholarly essay is a type of written work that is typically assigned to students in academic settings. It is usually longer than a regular essay and requires more research and analysis. A TREATISE is a formal and systematic written discourse on a particular subject, often written by an expert in the field. A THESIS is an essay or dissertation that presents an original argument or claim about a particular topic and is usually submitted as part of a degree program. Both treatises and theses are considered scholarly essays.
