The quality or condition of being unpleasant to taste or difficult to accept.
The unpalatability of the dish made it hard for anyone to enjoy the meal.
Unpalatability → It is formed from "un-" (meaning not), "palatable" (from Latin "palatabilis", meaning pleasing to the taste), and "-ity" (meaning the state or condition of). The word describes the state of being not pleasing to the taste.
Think of 'not' ('un-') being combined with something that is 'pleasing to the taste' ('palatable') to remember that 'unpalatability' refers to something that is not enjoyable to eat.
