Etymology Origin:
The word jejune originates from Latin jejunus, which initially described physical emptiness (e.g., fasting or hunger). Over time, its meaning expanded metaphorically to describe intellectual or emotional barrenness—something "empty" of substance or interest. The suffix -une (via French -une) solidified its adjectival form in English. The dual sense of "physically meager" and "dull" reflects its historical journey from literal to figurative lack.
