Idiom B1 — Intermediate

Over the Moon

Extremely happy, delighted, or elated about something wonderful that has happened.

Meaning

Literal: Physically above the moon — an impossible height suggesting limitless joy. The image evokes the idea of happiness so great it could lift you off the earth entirely.

Figurative: Extremely happy, delighted, or overjoyed. The phrase is used when someone receives wonderful news or experiences something that fills them with intense joy — a new baby, a job offer, a sports victory, a surprise gift. It describes happiness at the very high end of the emotional spectrum.

Origin & History

The expression is commonly linked to the nursery rhyme "Hey Diddle Diddle" (first recorded in the 16th century), in which "the cow jumped over the moon" — an image of impossible, exuberant, joyful leaping. Though the exact connection is debated, the moon has long represented an impossible or extraordinary height, so to be "over the moon" meant to be transported beyond all ordinary limits of happiness.

The phrase became especially well-known in British English through football culture. From the 1970s onwards, football managers and players frequently used it in post-match interviews to describe their reaction to a win — often paired with its opposite, "sick as a parrot", for a loss. The phrases became such famous clichés that they are now used with irony, but "over the moon" remains a genuine and widely understood expression of great happiness in everyday British English.

Example Sentences

How to Use It

Register: Informal. Very common in everyday spoken British English. Also used in casual written English — social media posts, texts, informal emails. In professional or formal contexts, use "delighted", "thrilled", or "very pleased" instead.

Grammar patterns: Used predicatively after "be": to be over the moon (about/that). Examples: "She was over the moon about the promotion." / "He's over the moon that they won." Can be intensified: "absolutely over the moon", "completely over the moon".

Hyphenation: When used before a noun as a compound adjective, hyphenate: an over-the-moon reaction. As a predicative adjective, no hyphen: She was over the moon.

Common Mistakes

Watch out for these errors

"She was above the moon about her results." (the fixed phrase is "over the moon", not "above the moon")

"She was over the moon about her results."

"He was over moon when he heard." (the article "the" cannot be dropped from this idiom)

"He was over the moon when he heard."

"They were over the moon of winning." (use "about" or "that": "over the moon about winning" / "over the moon that they won")

"They were over the moon about winning." / "They were over the moon that they had won."
