The state or quality of being delectable; extreme pleasantness or appeal to the senses.
From 'delectable' (from Latin 'delectabilis') combined with the English noun-forming suffix '-ness'. Both elements trace to Latin 'delectare' meaning 'to delight or charm.'
While 'delectability' and 'delectableness' mean almost the same thing, 'delectableness' sounds more poetic and old-fashioned—it's the kind of word Jane Austen might use to describe a fine pastry!
