QUESTION: What's the difference between ADEQUATE, SUFFICIENT and ENOUGH?


ADEQUATE, SUFFICIENT and ENOUGH are slightly different in meaning.

If something is adequate, there is enough of it, but only just enough.

If there is sufficient quantity of something, this suggests that there is as much of it as you need.

Usage of these adjectives often means quantity rather than quality, whereas appropriate and suitable suggest a qualitative response to something.

- The pay was adequate, but it certainly wasn't generous. The rate of pay - 6 pound an hour - was barely adequate to raise a family on.

- His answer to the question was adequate but it wasn't developed sufficiently to gain high marks.

- The Prime Minister gave an inadequate reply to the journalist's question.
