what is deference in 'since' and 'for' in English grammar?
Answers
Since can refer to a point after a specific time or event in the past. ... When using since, we normally use present perfect and past perfect tenses in the main clause of the sentence. You wouldn't use since when you are talking about the future because, by definition, since refers to specific point in the past.
Explanation:
since is used when the particular time. is not given for ex- I have been writing letter since morning. Here it is not told from how many hours in the morning. while for is used when particular time is given for ex- I have been writing letter for three hours.here it is clear that the person is writing letter from how much time. In short since does not tell the exact time but for tells the exact time.Don't forget to follow me and mark it as brainliest
