Mo Cuishle – Meaning, Origin and Usage

Are you looking for a pet name for your girlfriend, wife, or daughter? You could call them “Mo cuishle” to show them you care for them deeply. This post unpacks the meaning and origin of this expression.


The saying “mo cuishle” is a misspelling of the Irish saying “chuisle mo chroí,” meaning, “pulse of my heart.” However, the misspelling of the expression “mo cuishle” comes from a Hollywood movie. The phrase translates to English from Gaelic to mean “my darling” or “my love.”

You can use the phrase to describe women in your family, such as your wife or daughter. You could use it as a pet name for your girlfriend. However, the real meaning of “mo cuishle” is that someone is the “pulse of your heart” and they are your reason for living.

Without your “mo cuishle” by your side, you don’t feel like a complete person, and you don’t have any reason to live.

The expression “mo cuishle” originates from the Irish language, Gaelic. It’s a pet name for your partner or girlfriend in the local tongue. The phrase translates to “my pulse,” but it means that the other person is the pulse of your life and the reason for your being.

However, the spread of the expression in English comes from its use in the movie “Million Dollar Baby,” produced and directed by Clint Eastwood in 2004. The film stars Hillary Swank as a female boxer on her way to the tile.

Eastwood based the film on the Paul Haggis screenplay of short stories from F.X. Toole. F.X. Toole is the name of a cutman and fight manager, Jerry Boyd. The film stars Swank alongside other Hollywood A-listers like Morgan Freeman and Eastwood.
