STILL (todavía, a veces con el sentido de -uffffff todavía!?)
To use in affirmative and negative sentences. It often refers to something happening for
longer than expected.
-Notice the position of still before the main verb or adjective.

Do you still live with your parents?
It's 8pm, and I can't leave the office because I still have work to do.
Are you still angry with your partner?
He is still asleep so don't wake him up.
-If the verb has two parts, still goes between both the verbs:

Is it still snowing? (= it continues to snow, it hasn't stopped)
When I went to bed, Angelica was still working.
-But if one of the two verbs is negative, still goes before that negative verb:

YET (ya?- para preguntar si algo esperado ya ha sucedido / todavía no- para decir que
algo que esperábamos no ha sucedido todavía )
To use in questions and negatives Yet refers to an action that is expected in the future. It
is not used in the simple 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:

-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.

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:
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.
