What does unpleasantness mean?
Unpleasantness is the noun naming the quality of being unpleasant: something that causes discomfort, annoyance, dislike, difficulty, or emotional rejection. It can refer to a physical sensation, an atmosphere, a social manner, or the general effect of an experience. Unlike the adjective unpleasant, which usually characterizes a particular person, object, or event, unpleasantness tends to abstract that quality so that it can be discussed or evaluated. The expression “a degree of unpleasantness,” for example, suggests that an experience can be assessed according to how unpleasant it is. The word appears in both British and American English and has no significant regional distinction. Although less common than unpleasant, it is useful when an exact noun is needed, especially in formal discussion, criticism, research, and descriptions of sensory or social conditions.

Where does unpleasantness come from?
Unpleasantness was formed in English by adding the suffix -ness to the adjective unpleasant. Unpleasant combines the prefix un- with pleasant, a word that ultimately comes through French plaisant from Latin placere, meaning “to please.” English cognates and related formations include please, pleasure, and displeasure, all reflecting the same broad idea of giving or experiencing approval and enjoyment.
