WORDS THAT USE JEJUN-

What does jejun- mean?

Jejun- is a combining form used like a prefix representing the jejunum, the middle portion of the small intestine. It is used in medical terms, especially in anatomy and surgery.

Jejun- comes from the Latin jējūnus, meaning “fasting, empty of food,” as the jejunum was thought to be empty after death. And, incredibly and perhaps ironically, the word dinner and dine also ultimately derive from the Latin jējūnus, as does the adjective jejune, meaning “dull or immature.”

Jejun- is a variant of jejuno-, which loses its -o– when combined with words or word elements beginning with vowels.
