I searched online and I understood that "master's degree" retains the apostrophe, while the relative thesis is commonly referred to as "master thesis". However, of the forms

  • Master thesis
  • Master's degree thesis
  • Master degree thesis

Which one is wrong, which is right and which should be preferable to use on a thesis cover? I know that in English theses it's common to use the phrase "Thesis prepared for the Degree of Master of Science" but I can't do this. Thanks.

"Grammatically speaking, master's thesis unequivocally means a thesis of a master. Master thesis can be read the same way, but also as primary, principle or main thesis.

Stick with master's thesis."

    Correct. If you click through the search results you'll see that "master's thesis" also appears. The term has been aggregated to the "master thesis" search results. The n-gram search shows that "master's thesis" is more prevalent. books.google.com/ngrams/…

  • Indeed! I thought I shall change my CV now, but I see that I used "MS" there :) And in one place "master's thesis" correctly. The good thing is that it can be both lowercase (which I used) and uppercase (which looks more frequent). Commented May 17, 2022 at 15:13
