long research paper for a degree
A long, formal paper that a student writes to finish a university degree, especially a master's or PhD.
用法パターン：
to write a thesis on [topic]
よくある間違い：
Learners often confuse *thesis* (the whole long research paper for a degree) with *thesis statement* (a single sentence that gives the main idea of an essay). In academic writing classes, when teachers say "Write a thesis statement," they usually do NOT mean to write a full thesis.
類義語
dissertation (Very close in meaning; in many universities this is the usual term for a doctoral thesis, especially in American English.)
対義語
exam (An opposite kind of degree requirement: a test with questions instead of a long research paper.)

main argument of a text
The main idea or claim that a writer or speaker wants to explain and prove, usually in one clear sentence.
用法パターン：
the thesis of [a book / an essay] is that [clause]
よくある間違い：
Learners sometimes think *thesis* here means "topic" or "subject". A thesis is not just what the text is about; it is a specific claim or opinion that the writer wants to prove. They also sometimes write very broad or factual statements as theses, instead of arguable claims.
類義語
central argument (Emphasizes that this is the key line of reasoning, not just any idea in the text.)
対義語
antithesis (A directly opposing argument or idea, especially in formal discussion or writing.)

proposition put forward and defended
An idea or claim that a person says is true and then tries to support with reasons and facts.
用法パターン：
to advance a thesis that [clause]
よくある間違い：
Learners sometimes use *opinion* when they mean a carefully argued *thesis*. An opinion can be simple and personal; a thesis in this sense suggests a more serious claim that should be supported with reasons or evidence.
類義語
proposition (A formal term used especially in logic and philosophy for a statement that can be argued about or tested.)
