After is a preposition: it can be followed by a noun or an -ing form.

After is not an adverb: we do not use it with the same meaning as
afterwards, then or after that.

restaurant.

17 after all

After all gives the idea that one thing was expected, but the opposite
happened. It means ‘Although we expected something different’.

free after all.

We can also use after ail to mean ‘We mustn't forget that ... ‘It is used
to introduce a good reason or an important argument which people
seem to have forgotten.

18 afternoon, evening and night

Afternoon changes to evening when it starts getting dark, more or less.
However, it depends on the time of year. In summer, we stop saying
afternoon by six o'clock, even if it is still light. In winter we go on saying
afternoon until at least five o'clock, even if it is dark.

Evening changes to night more or less at bedtime. Note that Good
evening usually means ‘Hello’, and Good night means ‘Goodbye’ — it is
never used to greet people.
A:Good evening. Terrible weather, isn’t it?
B:Yes, dreadful.
A:Hasn't stopped raining for weeks. Well, | must be going. Good night.
B:Good night.
