These words are indications of when an action is going to happen, with each suggesting to the speaker the timing of a particular verb. They can be used to indicate an action which will happen, one which is expected to happen and one which is unexpected around the present time.
Still, yet and already:
This word is used when the speaker wishes to indicate an action or situation which is continuing into the present. The action remains unfinished and can often be used to refer to an action which is unexpectedly continuing.
Unlike ‘still’, ‘yet’ refers to an action which is expected in the future and is not used to refer to events in the past.
This word is used when a speaker wishes to talk about an action which has occurred before now. It can be used in the present or past but is not used in a future sense. It is used in affirmative sentences.
Still, yet and already: be careful!
It can be useful to note the position of the word ‘still’ as it is placed before the verb or adjective.
Should the verb in question have two parts, then ‘still’ can be placed between the two verbs.
If you are using a sentence where one of the verbs is negative, then you should place ‘still’ before the negative word.
Yet can be used in order to ask whether something expected has happened and is often used at the end of a question. It can also be used in order to suggest something expected has not happened.
‘Yet’ can also be used in conjunction with ‘still’ in order to explain why a particular action might be continuing.
It can also be used in order to give sentences a similar, affirmative meaning to the word ‘still’, though this has the effect of making sentences sound more formal and is not nearly as common.
The placement of ‘already’ can also change in some sentences. If ‘already’ is being used in a sentence with the present tense, then it should be placed between the subject and the verb.
For those times when you are using a present and a present perfect sentence, then it should follow directly from the subject.
Despite this, in the majority of sentences using the present perfect tense, the order will be ‘subject’ then ‘have’ then ‘already’ then the ‘past participle’.
