ESL-Once in a Blue Moon

Native English language speakers use idioms on a daily basis. In fact, we use them so regularly that we aren't even aware that some of them are idioms, or slang, or even euphemisms.

One expression that is based on reality is "once in a blue moon." An example of this idiom would be "I only tutor ESL students from Germany once in a blue moon." This means that I do tutor ESL students from Germany, but only occasionally.

Literally (or almost literally), a blue moon refers to the second full moon that occurs within a calendar month. This event only happens about once every two-and-a-half years. As for why astronomers call a second full moon in a month "blue," you'll have to visit someone else's blog!

Idioms are extremely useful for English language learners to learn. I'd say that every single day someone communicates in English, they will use or encounter an idiom and/or slang.
