annoyance
Word family
Synonym discussion
Sense: noun/1
All four words name unhappy feelings, but they differ in cause, strength, and tone. 'Annoyance' is everyday and mild — the prickly feeling caused by something small that keeps bothering you, like a buzzing fly or a forgotten reply. 'Irritation' is its closest relative and often interchangeable, though it can suggest a slightly sharper, more visible reaction. 'Frustration' is stronger and aimed at being blocked: you feel frustration when you cannot reach a goal, not just when something is annoying. 'Displeasure' is the most formal and the most controlled — a boss might 'express displeasure', while a friend would simply 'show annoyance'. So you can say, 'Citlali felt annoyance at the constant interruptions', but, 'Citlali felt frustration that the project was going nowhere'.

Etymology
'Annoyance' came into English from Old French 'anoiance' in the 1300s, built on the verb 'anoier' (to trouble or bore), which itself goes back to the Latin phrase 'in odio' meaning 'in a state of hatred or dislike'. The earliest English uses described the act of harming or troubling someone; over time the word softened, and by the modern period it mostly named either the bothered feeling or the small thing that causes it.
