Student or Learner
Would you be so kind to tell me what you think about the following sentence?
I am mainly interested in the preposition "on"
What I need is your corrections on my writings
Thank you in advance.
I think it's acceptable ("on"), but I'm not sure what you mean by "writings". If you mean essays, use 'essays'. If you mean your style of writing, use 'style of writing' or simply 'writing'.
