English Vocabulary


Who would be so kind as to tell me what is the same in these expressions?
Once in a while
Once in a blue moon
If once you know, please let me know.


  • Both expressions have more or less the same meaning; Juline.

    Once in a while = every now and then = from time to time = not very often = occasionlly.

    Once in a blue moon = very rarely
    I think the latter is nearly the same as never, like: when pigs fly = when Philip Cheeter has had it with women.

    A blue moon is a second full moon in the same calendar month. Yesterday we had a full moon. We'll have a blue moon on next August 31. That's worth knowing, isn't it, Juline?
  • Yes, it's worth knowing, AhQ. Tks.
