theses definition

Your thesis proposal will likely include terms that are not widely known outside of your discipline. These terms include particular theoretical constructs, formulas, operational definitions that differ from colloquial definitions, schools of thought and discipline-specific acronyms. This part of your proposal offers the reader a list of definitions of these terms.

• How you define such terms could considerably affect how the reader understands your thesis

• Be sure you use these terms in a consistent fashion throughout your proposal and thesis

He wrote a thesis on the lyric poetry of our country comparing it with that of Europe.
