I was just correcting an Italki student's short article; Chinese speakers often use 'very' when we require 'really', and it was very/really difficult to explain why. It seems 'really' can also modify/...
In what situation would you use 'so' instead of very? For example,
I'm very sorry.
I'm so sorry.
(When you apologize to someone)
Does 'so' sound natural in the context?
Is he an old man?
Yes, he is ...
