Let's posit:
- You're a university student. I don't posit degree level; you can be undergraduate or postgraduate.
- You must not overstep the essay's word limit, whatever it is. You lose marks if you overstep.
- Your word limit is too short to elaborate an argument or idea.
How do academics write that the word limit precludes elaboration? Is this common or professional? Something like
The word limit prevents me elaborating this idea.
I cannot elaborate this argument here given the word limit.
Or is this stupid? Will the professor already know the word limit precluded you from elaboration?
