The idiomatic expression, once in a blue moon, means
- a.rarely
- b.frequently
- c.regularly
- d.never
Answer: (A) rarely
'Once in a blue moon' means very rarely. A 'blue moon' is the second full moon falling within a single calendar month, which happens only about once in two to three years - hence the idiom. It does not mean 'never' (the event does occur), and 'frequently' and 'regularly' are opposites. Similar expressions: 'few and far between' (rare), 'now and then' (occasionally).
