This question was motivated by a desire to have a clean set of terms to describe the life cycle of a manuscript from draft to publication from the perspective of the author.
I could say:
I am "revising" my paper and "resubmitting" it.
Obviously, this could apply to (a) the situation where you have submitted a paper and been given the option to submit an updated manuscript (i.e., a revise and resubmit); or (b) you received a rejection letter and you are improving the manuscript with the intention of resubmitting the manuscript to a new journal.
I was wondering what concise language can be used to distinguish these two types of revising and resubmitting?
