EK-spee-ayt
(verb) To atone for or make amends for wrongdoing.
He volunteered at the shelter to expiate his earlier mistakes.
Fun Fact
“Expiate” often appears in religious or moral discussions, especially in literature. It’s a core theme in stories about redemption—whether a hero making things right or a villain seeking forgiveness. Think of Jean Valjean in Les Misérables.
KAS-tih-gayt
(verb) To reprimand someone severely; to criticize harshly.
The editor castigated the writer for missing yet another deadline.
Early 17th century: from Latin castigare, from castus ‘pure’ + agere ‘to drive’.
Fun Fact
Castigate doesn’t just mean to critique—it means to come down hard, often with a tone of moral authority. In the past, it could even refer to physical punishment, but today it’s used more metaphorically: a boss tearing into an employee, a coach yelling during halftime, or a pundit scolding a public figure. It’s always loud, sharp, and meant to correct.
