Idiom: Over the Moon

Illustration of a joyful couple emerging from the top of a full moon, holding an engagement ring box under a starry sky, symbolizing the idiom 'over the moon' to express their happiness upon getting engaged.


(be) over the moon: To be extremely happy or pleased.


With the picture above it's not difficult to remember this idiomatic expression. The young couple standing over the moon is delighted because they have just gotten engaged to be married. The moon is located way up in the sky and that shows the height of their happiness. 

From this, it can be understood that when someone is over the moon they are so delighted or happy that they feel like they could jump over the moon.


  • This is a very common expression in English, especially in British English.
  • The expression is informal and is often used in spoken English or in casual written contexts.


It's not clear exactly where this expression came from but it is believed to come from older expressions related to the moon that illustrated something beyond someone's reach. So being "over the moon" implies a state of happiness that is more than someone would expect.

It's often used to describe someone's elation after hearing good news, achieving a goal, or experiencing something wonderful.

At the same time, the idiom can be used for ordinary everyday situations, as you can see in the examples below. The situation does not have to be extraordinary. I could be something very ordinary but the feeling is one of real happiness.
