Jejune

dʒɪˈdʒuːn

adjective

lacking interest or significance; dull; insipid

The word 'jejune' comes from the Latin word 'jejunus', which originally meant 'fasting' or 'hungry', and eventually evolved to mean 'lacking in substance' or 'dull'. It is often used to describe something that is uninteresting or superficial.

The jejune jesuit.

Ulysses
