The conjunction after can be used to join two clauses. After and its clause can go either before or after the main clause.

• I went to Canada. I finished my studies.
• I went to Canada after I finished my studies. OR After I finished my studies, I went to Canada.
• He fed the dogs after he returned from work.
• After watching the movie, we went home.

When after and its clause goes at the beginning of a sentence, we use a comma to separate it from the rest of the sentence.

After all and finally

After all does not mean finally, at last or in the end. After all means ‘in spite of what was said before’. Finally is used to introduce the last element in a series.

• After the show, we had dinner and went to a dance bar; then we finally went home.
• I’m sorry. I can’t come after all.
• You should make your bed now. After all, you are a grown up boy.

Afternoon and evening

Afternoon starts after lunch. It changes to evening after normal working hours. Evening changes to night at around bed time. Note that Good night is not used to greet people. It is used in the sense of ‘Goodbye’.
