a. We use 'still' to show that something continues up to a time in the past present or future. It goes in front of the main verb. (e.g. The children still enjoyed playing games. They are still living next door. We will still be on holiday.)
1. or after the present simple or the past simple of be:. (e.g. Her grandfather is still alive. They were still unhappy.)
2. Still is also possible in negative sentences (before the negative)
b. We use 'yet' mainly in negative sentence and questions, usually with perfective aspect, to show that something has not happened by a particular time. 'yet' comes at the end of the sentence. (e.g. It was late, but they hadn’t arrived yet. Have you fixed the car yet? She won’t have sent the email yet.) yet = until now.
1. We often use Yet with the present perfect. (Have you met ~ yet?)
2. 'She hasn't come yet'. But 'still ~ not' shows a stronger feeling of surprise or importance.
c. We use 'already' to show that something has happened sooner than it was expected to happen. It comes before the main verb. (e.g. The car is OK. I’ve already fixed it. It was early but they were already sleeping.)
1. or after the present simple or past simple of the verb be. (e.g. It was early but we were already tired. We are already late.)
