• Quite has two meanings. Compare:
      It’s quite good. It’s quite impossible.

    Good is a ‘gradable’ adjective: things can be more or less good. Impossible is not ‘gradable’. Things cannot be more or less impossible; they are impossible or they are not.
    With gradable adjectives, quite means something like ‘fairly’ or ‘rather’.

      ‘How’s your steak?’ Quite nice ‘
      She’s quite pretty. She’d look better if she dressed differently, though.

    With non-gradable adjectives, quite means ‘completely’.

      His French is quite perfect. The bird was quite dead.
  • We put quite before a/an.

  • We can use quite with verbs.
