use of since

[Rachanaagarwal01]

I have lived in india since 1990.

I have been living in india since 1987.

are both above mentioned sentences correct?
if yes then when or which situation we need to use ?

Hi,

'India' needs a capital 'I'. Both are grammatically correct. In the second sentence you are emphasising that you are going to continue living in India.

I got stuck again in use of since/for:

He was eaten nothing since yesterday.
I have not seen her since last week.

So here how they are using 'since' as since shows point to time but here not along with this i thought since and for we can use with any perfect continous tense but here they are not using 'has/have/had +been'

why so?

S-3 she has been here an hour.

in this why we are not using 'for' before time i.e. She has been here for an hour.

Nobody has answered your question till now.
Nobody has answered your question since you posted it.
Nobody has answered your question for a long time.

In spite of that, and despite the fact that I am a learner as well, I'll try to explain to you usage of "since" and "for" with perfected tenses.
Of course my explanation should be taken with reserve.

I'm not going to add much to what E2e4 wrote, but reading a different explanation may help.

Per your initial question, there is no difference. The second option has more emphasis. But either is fine to use for any reason.

Per your "since" and "for" question:

"Since" identifies a point in time.
"For" identifies duration of time.

He has not eaten since yesterday. Means that yesterday was the last time he ate.
I have not seen her since last week. Means that last week was the last time you saw her.
She has been here an hour. This is not a clear statement for a non-native speaker. It should be "She has been here for an hour." Often native speakers drop the "for". Just lazy language. But you understood the sentence without the "for". So be confident in your ability.

There are no exceptions that I can think of to since/for. If the word is left out consider the time clause.
"Last week" is always a point in time. "A week" is always a duration of time.
"Yesterday" is always a point in time. "A day" is always a duration of time.
Only a very poor speaker or an odd dialect would leave out "since." Native speakers would be confused if someone left out "since."
