In English,what is the difference between (in the night) and (at night)?Thanks in advance?

Answer 1

The usual preposition with 'night' obviously is 'at' - so 'at night' is used whenever we refer to this as a period. No rules in English regarding the periods of night/day, so we say:
- in the morning, in the evening, in the afternoon, but:
- at night, at noon, at midnight, at dawn, etc.

The phrase 'in the night' is used when we refer to a specific night in question, eg. "Where were you in the night of the murder?"

Answer 2

I can't think of any phrases where I would say 'in the night'. Perhaps you can give an example that you have seen...

We would say - 'I will do that in the afternoon', or 'in the morning', meaning 'I will do it later, in the morning or afternoon', but 'I will do it in the night' sounds strange and unidiomatic. I cannot say why. 'During the night sounds' better.

So at present I think 'in the night' should be avoided if you want the kind of idiomatic English that I am used to (in Bristol, UK). It might be different in other places....

Answer 3

In the night implies that something is within an environment during night time.
At night is during a time period of darkness between sunset and sunrise.

Answer 4

Most of the time you would use 'at night' or 'during the night.' The only time I can think I would use 'in the night' is in a sentence such as ' A loud noise woke me up in the night,' where the phrase refers to the night just passed: if it often happens, then you're back with 'at night' - 'I often get woken up at night by loud noises.'
