Sense: noun/2

All four words describe difficult interpersonal situations, but they differ in intensity and focus. 'Unpleasantness' is the mildest and most general term — it can refer to anything from a brief awkward silence to an ongoing conflict. 'Tension' emphasises a strained atmosphere where conflict could erupt at any moment, without specifying whether any actual argument has occurred. 'Friction' focuses on repeated small disagreements that wear down a relationship over time, like two surfaces rubbing together. 'Hostility' is stronger and more formal, suggesting open opposition or aggressive intentions. 'Nastiness' is the most personal and emotionally charged, implying deliberate meanness or spite. For example: 'There was some unpleasantness when the bill arrived' (mild, vague); 'The tension in the room was unbearable' (atmosphere); 'Constant friction between the departments slowed the project' (ongoing); 'His hostility towards new ideas was obvious' (open opposition); 'I was shocked by the nastiness of her remarks' (deliberate cruelty).

Etymology

Old FrenchMiddle EnglishEnglish

Formed in English by combining the prefix 'un-' (meaning 'not') with 'pleasant' (from Old French 'plaisant', meaning 'pleasing') and the suffix '-ness' (forming a noun meaning 'a state or quality'). The word has been used since at least the 1700s to describe both disagreeable experiences and interpersonal conflicts.
