Hello,

Do the following phrases mean exactly the same?

  • To be in the market for
  • To be in need of
  • To be in the demand for

And ‘to be in the need of’ is incorrect, right?

Thank you very much.

Hi,

  • To be in the market for suggests that you are ready to buy something or sell something.
  • To be in need of suggests that you require or need something. You don’t use ‘the’.
  • To be in demand suggests that you are very popular or something is very popular. It is used without ‘the’ or ‘for’.
