Hello

Is there any difference between saying;

-I'll do my research later this week.
and
I'll do my research after this week.
?

When should I use the word 'later' ?
And one more, what's 'later on', could you please tell me the cases in which I must use it?

Thanks.

Hi,

yes there's a difference!

When you say that you will do it later that week you express that you will have done it at least in this week.

When you say after you mean that you'll do it next week, a better way to say this is " I'll do my research next week"

I try to make an example for "later on", maybe you can guess in which cases you can use it.

When can I use the sewing machine?—Later on, when I'm done.

Greetings

later this week implies that you are going to do the research sometime this week

after this week says that you are going to do your research sometime next week

you should use the would later when you're being evasive and don't want to give an exact clear and concise answer

i have no idea when to use later on, personally have never had the need to use it

sorry

hope this helps

Hello, I'm an American English speaker and an EFL instructor in Japan.
Generally, (not always) I believe that "later" is used in combination with specific time periods, or by itself to just man "sometime".
After seems to be used with vague or non-specific time periods. Also, "after" can be used with SV clauses. Therefore for me, these sentences seem correct:

I'll do my research later. (= sometime)
I'll do my research later this week. (= sometime this week)
I'll do my work after a while. (vague time reference)
I'll do my research after this week is over. (after + SV)

In my mind, the expression "after this week" without a following verb seems incomplete.
