Jejune

Jejune is an adjective that means naive or simplistic.

Our word of the day comes from the Latin word jejunus (jay JOO noose) which means ‘without food.’ From this, the word later came to refer to opinions or thoughts that were ‘without intellectual nourishment.’ Here’s an example: Being a college junior with a love of philosophy can lend itself to lots of jejune opinions. But then again, most people at that age don’t have much intellectual depth to their ideas anyway.
