The quality of being suitable or fit for a particular purpose; capacity or capability.
From Late Latin habilitas, derived from Latin habilis 'suitable, able.' This form declined as ability became the standard English term, though it persists in specialized or archaic contexts.
Hability is almost a ghost word—it meant the same thing as ability but faded from English as simpler, more direct words took over, reminding us that language naturally prunes its vocabulary.
