YET AND ALREADY WITH PRESENT PERFECT.




YET FROM WOODWARDENGLISH.COM

Yet refers to an action that is expected in the future. It is not used in the past.
To ask if something expected has happened. It is usually placed at the end of the sentence or question.

  • Are we there yet? (A typical question kids ask while taking car trips with their parents)
  • Is the report ready yet?
  • Hasn't your mother told you yet? We're moving to Alaska!
To say that something expected hasn't happened:

  • Mary can't go home yet, she hasn't finished her work.
  • They haven't paid me yet. (I was expecting to paid before now.)
  • My parents haven't kicked me out of their house yet.
Yet is occasionally used in affirmative sentences, giving the sentences a similar meaning as the use of still. Note that this is more formal and not common.
  • We have yet to hear the big news from Aunt Martha.
    = We are still waiting to hear the big news from Aunt Martha.
Often, we use still and yet together to explain why an action is continuing.
  • I am still studying at the university because I haven’t graduated yet.
  • We still don’t know who will be our new boss. The owners haven’t told us yet.
  • I haven’t decided yet if I’m going to quit my job to go travel. I’m still thinking about it.

ALREADY

Already is used to refer to an action that happened sooner than expected.
It is used in affirmative sentences in the present or past, but never future.

  • A: Ask Katie to send the article to her editor. B: She has already sent it.
  • I already know what I'm going to buy you for your birthday.
  • They've already seen "Spiderman 15" and really don't want to see it again.
Notice the placement of already in the examples below:
  • Is Mary already here? She must have driven very fast to get here before me.
  • How does he already have the answers to tomorrow's test?
  • Have they already obtained their visas?
In present tense sentences, it is placed between the subject and verb.
In present and present perfect questions, it comes immediately after the subject.
However, in present perfect sentences, the order is subject + have+ already + past participle.
