Let's see the previous one

Sorry for not attending to the blog in time as promised. Nonetheless, we do make a discussion here on the previous post.

As mentioned, the tense in “This has been happening since last six months with greater frequency” is present perfect continuous tense.


In this sentence, the word ‘since’ should have been replaced with ‘for’. If ‘since’ is a must, then the sentence should read as “This has been happening since February this year with greater frequency” or so. Whenever we use ‘since’ in present perfect continuous tense, the time should represent the starting point and not the duration. If it is representing the duration then we can’t use since and in its place should ‘for’ should be used.

Let me quote three examples from Wren and Martin:

He has been sleeping for five hours.
They have been building the bridge for several months.
They have been playing since four O’ clock.

Any standard English grammar would clarify this.
