put off: meaning and explanation
to put something off = to postpone or delay something.
When you delay doing something because you’re too busy or because you don’t want to do it, you are putting it off.
If you want to specify that you are delaying something until a specific day/time, you can use the ‘to put sth off until/to + time’. e.g. I’m too tired to do my homework, so I’m going to put it off until tomorrow.
A more formal synonym for ‘to put something off’ is to procrastinate. e.g. You need to stop procrastinating and get on with your essay!
