Why is it castigated instead of deposed?

Deposed means to fire someone.

Castigated means (at least one of its synonyms) to punish, to discipline someone.

OE


The sentence indicates that the employee is young and makes mistakes. “Verdant” means either green and lush, like a forest, or new and inexperienced (the use of green as a metaphor, as in, she’s still green at her job). “Banal” means unoriginal, which does not fit with the rest of the sentence, and “sagacious” means shrewd, which is the opposite of how the employee acted. Since the mistake was so expensive, it makes sense that the employee would be “castigated,” or severely criticized. He wouldn’t be “deposed”—that word is for kings, dictators, etc., forced out of power. And the employee would not be “enamored,” or filled with a feeling of love, for the mistake he just made.
