Is it right to write the negative form of the present perfect like this:
"haven't/ hasn't + p.p+ yet" ??!
or this one is the right form of it:
"haven't/ hasn't + p.p " because we only use yet to make that negative form of just or already???
Thanks for these helpful info. but wanna make sure of something too.
Do we have to use never only to get the negative form of ever??
e.g. Have you ever been to London?
No i have never been to London or can i say
no i haven't been to London.
Yes, Its's possible, you can use 'haven't/hasn't+ p.p+ yet.'
eg. Haven't you finished your homework yet?
She hasn't taken off her hat yet.
But still you can use, 'She hasn't taken off her hat' because it means she has not taken it off, untill this moment. Both are correct. "yet" is not only used to replace 'just' or 'already' when converting present perfect to negative, it also can use meaningfully.
Thanks for your kindness.
'Never' indicates negation. It means "not ever". It emphasizes the negation and yes, it is the negative of "ever". It should only be used to get the negative meaning of ever and moreover cannot replace the word "no".
