Merriam-Webster defines edit as
an instance or result of editing
Google the term "edit meaning" gives the following definition of edit
a change or correction made as a result of editing
Oxford Learner's & Cambridge dictionary define edit as
an act of making changes to text or data
Merriam-Webster's definition and google search seem to suggest an edit is a change. Thus there can be 5 edits in a paragraph. In contrast, Oxford's and Cambridge's definitions seem to suggest an edit is a process so an edit can involve one change or multiple changes in a paragraph.
Is this a difference between British English and American English ? Or could edit be used for both definitions, although perhaps not "interchangeably"?
