What does exasperator mean?
An exasperator is a person or thing that exasperates — that is, that irritates or frustrates someone to the point of impatience or annoyance. Formed from the verb 'exasperate' with the agentive suffix '-er', it names the source of the frustration rather than the feeling itself. The word can refer to people ('a habitual exasperator') or to circumstances and objects ('the printer, that great exasperator of office life'). Because the far more common forms are the verb 'exasperate' and the adjective 'exasperating', 'exasperator' itself is rare and tends to appear in playful, informal, or deliberately literary writing, where it lends a slightly wry tone. Its connotations are negative but usually mild — it suggests chronic, low-grade provocation rather than serious hostility. Readers will most often encounter it as a coinage or nonce use, but its meaning is transparent to anyone familiar with 'exasperate', making it a useful and expressive option when a compact label for an incorrigible irritant is needed.

Etymology of exasperator
'Exasperator' derives from the Latin verb 'exasperare', meaning to make rough or to irritate, formed from 'ex-' (intensively) plus 'asper' (rough). The verb entered English in the early 17th century, and the noun was formed with the regular English agentive suffix '-er'. It shares its ultimate root with words such as 'asperity' (harshness or roughness of manner) and, more distantly through the same Latin adjective, other terms for roughness.
