The quality or state of being execrable; the degree to which something is utterly detestable or hateful.
From 'execrable' (from Latin 'execrabilis') plus the suffix '-ness,' which forms nouns expressing qualities or states. The root 'execrari' means 'to curse.'
Medieval writers would use 'execrableness' to describe truly horrifying things—the suffix '-ness' let them measure evil itself, as if sinfulness came in degrees they could quantify.
