The quality or state of being able to be hung or suspended, or the suitability of something for hanging.
From 'hang' (Old English 'hon') plus the productive suffix '-ability' (from Latin 'habilis,' meaning capable), forming an abstract noun describing physical properties.
The art world uses 'hangability' to describe whether a painting can be displayed—it's the kind of jargon term that professionals create by suffixing '-ability' onto any verb, and it works perfectly for specialized communication.
