Hello everyone, I think this is a quite simple question, but it is confusing me that I am not sure whether I should use the noun form, verb form or adjctive form. While I am searching on google, it show everything on different websites. So I need a little help. Thank you. I want to tell my students that they better use transition words in their essay. And I would say: "You better add transition word / transitional words in each paragraph" "In this sentence, you should add compare transitions / comparison transitions / compare transitional words / comparsion transitonal word" "And also, you may want to add consequence transitional words / transional words of consequence at the ending paragraph." Actually, I just want to clarify which form is in normal usage if all of them are correct. Thank you very much.
