"put off","put back", "push back" what's the difference? Thanks!
For example, which phrasal verb should I put in this sentence "our project is ______ for one week"?

Question

Answer

In the U.S., we'd say, in this order of frequency, with potentially slight differences in meaning depending on context

The project was pushed back one week
The project was put off for one week.

We rarely use "put back" in this context. We use it to mean "replaced".
