Since as an adverb

[Jesus1]

Hello! How is it going?

My question:

'We had a letter last week. We haven?t heard since'

Can I use ?since then?instead of ?since? in
the sentence above?

Has?since?
and ?since then? got the same meaning?

By the way, I always say:

'in the sentence ABOVE'

Is that right? Or should it be 'in the ABOVE sentence'?

I know 'above' doesn?t work as an adjective but
I?m afraid things like that I have seen them written
both ways, i.e 'in the sentence above' 'in the
above sentence' Thanks a lot!

Jes?s.

Hi Jesus

Yes "since" and "since then" here mean the same thing.

Also "sentence above" or "above sentence" are both correct.

Hello! Thanks both of you!

By the way, Could I use 'ever since' in that
sentence as well? Has it got the same meaning?

Thanks in advance

Hi Jes?s

My "feeling" says "ever since" is better used in a positive sentence rather than a negative one. Also, the word "ever" adds emphasis to the 'time since then' which would also usually mean that you'd use the present perfect continuous.
.
I'd possibly use it this way:

"We had a letter last week and we've been waiting nervously for the next one ever since."

"We got a letter last week and we've been trying to decipher it ever since."
