Student or Learner
I have yet to see the result = I have not seen the result
Is it correct?
Would you tell me more how to use the word "yet" ?
"He told me he would send the check last week, but I have yet to receive it."
If you would like to learn more about the various uses of 'yet', I suggest you go to this site: http://dictionary.reference.com/
or any of the many reference sites available on the Web. Then, if you still think you need more examples, feel free to write again with specific usage questions.
All best wishes,
