When we say something happens “once in a blue moon“, we mean that it happens very rarely or not very often. It’s like seeing a blue moon, which is a rare event that doesn’t happen every day.
Here are two examples in sentences:
Example 1:
Sarah reads books once in a blue moon because she is usually busy with her work.
Example 2:
We see snow in our town once in a blue moon as it is located in a tropical region.
Now, let’s see two examples in a conversation:
Example 3:
Ben: Hi, Mia! Do you go to the cinema often?
Mia: Not really, Ben. I go once in a blue moon when there’s a movie I really want to see.
Example 4:
Alice: Hey, Jake! I heard you cooked dinner last night.
Jake: Yeah, Alice, but I cook once in a blue moon. Usually, I just order takeout.
Remember, when something happens “once in a blue moon“, it means it happens very infrequently or rarely. It’s a way of saying that something doesn’t occur often, much like a blue moon, which is a rare event in our sky.
