Origin
From Latin ineffabilis, from in- (not) and effari (to speak out).
History
Medieval and early modern writers used ineffable for sacred mysteries that speech could not hold. The sense widened to awe, grief and beauty that resist neat description. Poets still prefer it when ordinary adjectives feel blunt. It asks the reader to accept a limit on naming rather than to invent more labels.
