I'm writing a paper on a theme that has a lot of research. To define a concept, I use the definitions of several writers, all properly cited.
Then I define more related concepts, and then I want to add more to the definition I give before.
Eg. As established before "the first definition" and the previously exposed concepts, it can finally be defined as the final definition.
I have looked all through the APA 7th edition, and I must have skipped how this should be done appropriately.
