Why this word is great
MAVOURNEEN — [Noun] A term of endearment for a darling or sweetheart, steeped in the particular warmth of Irish and Hiberno-English. From Hiberno-English, borrowed from the Irish phrase mo mhuirnín, meaning "my darling," where mo is "my" and mhuirnín is a diminutive of muirn ("affection"). Unlike "darling," a hollowed coin of general English, or "acushla," which stakes its claim on the vital pulse, "mavourneen" is a soft, proprietary clasp of cherished fondness itself. It is the word murmured into the crown of a child's hair at bedtime; the whisper in a lamplit kitchen holding the damp of an Atlantic evening; the name breathed in a final letter, the ink blotted with distance—a tender diminutive for a world that is always diminishing, proving the smallest of words can be a homeland.

"Such a nice clean corpse, did you ever see?
"Arrah, Tim, mavourneen, why did you die?"
