The odd word in the given list is “thesis”. A thesis is a long piece of writing that is submitted as part of a graduate degree program. It is a formal argument that presents the writer’s original research and analysis. A magazine is a periodical publication that contains articles, stories, and other features of general interest. A novel is a long fictional story that is typically published in book form. A dictionary is a book or electronic resource that lists the words of a language (typically in alphabetical order) and gives their meaning, or gives the equivalent words in a different language, often also providing information about pronunciation, origin, and usage.
The other three words are all examples of published works that are typically read for pleasure or education. A thesis, on the other hand, is a formal academic document that is written to demonstrate the writer’s mastery of a particular subject. It is not typically read for pleasure, but rather for its scholarly content.
