We use the adverb really when we want to emphasise something:
That pasta was really delicious. Thank you.
I really like those photographs. Can we see them on the computer?
Emigrating to Canada was a really big decision for the whole family.
We also use really to question whether what someone says is true:
They don’t look pleased to me. Are they really pleased?
Is that really her sister? They don’t look at all alike.
We can use really to make a negative utterance less direct:
I’m not really angry, but I wanted them to think about their behaviour.
A:What do you think she should say to him?
B:I don’t know, really.
We can use really as a short response when we show interest or surprise:
A:They’re going on a cycling holiday to France.
B:Really?
A:Yes, and they’re going to the Alps!
