Etymology
Origin of unspeakable
1350–1400; Middle English unspekeabill. See un- 1, speak ( def. ), -able ( def. )
Explanation
Something that's unspeakable can't be accurately put into words, like the unspeakable sadness of losing your beloved cat. You can use this adjective for things that can't be spoken or articulated, including the unspeakable joy of reuniting with your lost cat or certain unspeakable swear words that aren't allowed at school. But it's most often used to capture a feeling of horror that remains inexpressible even when people try to talk about it. The unspeakable evil of genocide is one example; when we can't comprehend why it happens, it's impossible to describe in words.
