Fun Fact
“Immutable” comes from the Latin immutabilis, combining in- (“not”) and mutabilis (“changeable”). The word has been used to describe enduring principles, truths, or conditions. Its philosophical roots remind us of humanity’s quest to understand what is permanent in an ever-changing world.
(adjective) Lacking substance, interest, or mature thought; naive and simplistic in a way that reveals inexperience.
The critic dismissed the debut novel as jejune — competently written, technically adequate, and utterly devoid of anything worth remembering.
Jejune derives from the Latin jejunus, meaning “fasting” or “empty” — literally describing a stomach that has not been fed. The same root gives us jejunum, the section of the small intestine named for its tendency to be found empty after death. It entered English in the 17th century carrying its literal sense of emptiness before acquiring its figurative meaning of something intellectually or creatively hollow — content that has the form of nourishment without any of the substance.
