Why “unutterableness” is a great word
UNUTTERABLENESS — [Noun] The state or condition of being incapable of being spoken or expressed. From unutterable (from un- ("not") + utterable ("capable of being spoken")) + -ness (suffix forming abstract nouns). Unlike "ineffability," which often implies a sacred transcendence, or "unspeakableness," its direct colloquial counterpart, unutterableness is the formal term for any quality that defies articulation. It is the choked silence before a private grief, the banal horror of a bureaucratic maze, and the simple warmth of a loved one's shoulder—a testament that the most real things often reside just beyond the reach of words.
