a. We will do it later on next week.
b. We will do it later on, next week.
Are both these sentence acceptable as written?
Is there a difference in the meanings they convey?
There is a comma after 'on'.
I think (a) implies that we will do it late in the week.
Is 'next week' added as an afterthought in (b)? It seems to me that that is the case. If it is then is the sentence acceptable in written English?
