The quality or state of being drinkable; suitability for drinking.
From 'drinkable' plus '-ness' suffix (Old English '-nes'). While 'drinkability' is more common in modern usage, 'drinkableness' appears in formal and technical writing.
The distinction between 'drinkableness' and 'drinkability' shows how English evolved—the '-ness' suffix is Anglo-Saxon heritage while '-ity' comes from Latin, so scientists often choose '-ity' to sound more authoritative and technical.
