“at all costs” or “at all cost”, which one is appropriate?

1 Answer

  1. It depends on what you mean. ‘At all costs’ is correct when you are emphasizing that you want to do something no matter what. However ‘at all costs’ should not be used when you are trying to say that it is a requirement. In this situation ‘at all cost’ should be used.

    For example:

    • I will be there at all costs.
    • I will be there at all cost.
