A reviewer of my thesis told me that I am wrongly using the word problematic. He suggested that I use problem instead. I have since read the definition of both words and neither correspond to the French definition I was looking for, so I am asking this community if it is correct to use this word to refer to the object of research in the context of a thesis.
If not, should I use problem instead, or a completely different word? Here is an example sentence:
This thesis provides potential solutions to the problematic outlined.
I know that some of you might think that it is not a real question, but please remember that word usage is of the hardest part of English writing for native French speakers.
