defer / postpone / put off
They have the same meaning.
I'm curious that those words are used in a casual conversation, too.
'put off' is a phrasal verb, so I guess it is commonly used in our daily lives.
Then what about 'defer' and 'postpone'?
'postpone', I've heard that many people use it when we talk to each other in a casual situation, but I've never heard of someone says 'defer.'
Is is okay to say like: I defer the year when I would move to another country.
I don't even know if this example sentence is correct or not.
Thank you so much!
