What does expiator mean?
An expiator is a person — or, by extension, a thing — that makes amends for wrongdoing; that is, one who performs expiation. The term belongs to a small family of formal English words drawn from Latin, alongside the more common verb "expiate" and noun "expiation," all ultimately rooted in ideas of ritual purification and sacrificial payment for guilt. To call someone an expiator is to place them in a morally weighty role: they shoulder responsibility for an offense and act to neutralize it, whether through suffering, restitution, or ceremonial rite. The word carries solemn, elevated connotations and is found chiefly in religious discourse, moral philosophy, and literature concerned with sin, redemption, and collective guilt. Because it is uncommon, writers often reach for near-synonyms such as "atoner" instead, but expiator retains a distinctive precision, naming not the act of atonement itself but the agent who undertakes it.
nounA person or thing that makes amends or atonement for wrongdoing; one who performs an act of expiation.

"The tradition cast priests and kings alike as expiators of communal transgression."
Every 'expiator' carries the Latin word for sacrifice in its bones — it literally names someone who pays a debt of guilt down to the last coin.

Etymology of expiator
"Expiator" derives from the Latin expiator, meaning one who purifies or makes atonement, formed from the verb expiare, which combines ex- ('out of, thoroughly') with piare, 'to appease or purify by religious rites,' itself related to pius, 'devout, dutiful.' English adopted the word in the early modern period as part of the broader borrowing of Latinate religious vocabulary. Its cognates include expiate, expiation, and expiatory, as well as the more distant relatives pious and piety, all descending from the same Latin root concerned with dutiful appeasement of the divine.
