Unspeakable
adjective /ʌnˈspiː.kə.bəl/ — Too extreme, horrifying, or sacred to be put into words
Definition
Not able to be expressed in words — either because it exceeds the capacity of language (horror, transcendence) or because social convention forbids its articulation. The unspeakable is where language reaches its edge.
Beyond the definition
Unspeakable is the word that acknowledges language's limits — the gesture toward what cannot be contained in words. Some horrors are unspeakable because they exceed description; some joys are unspeakable for the same reason.
Origin & history
English: un- (not) + speakable. The compound word is simple but the concept it names is not. Some things resist being spoken — not because they can't be, but because the speaking would be inadequate to the thing.
