One who gives a good talking-to?

ORATOR

This skilled speaker might address a crowd with eloquence, often found in ancient Roman forums or modern debate stages.

This clue plays on the double meaning of "talking-to." While it can mean a scolding, here it hints at someone skilled at giving speeches—an orator. The word "good" suggests they’re effective or impressive at it, not just any speaker. It’s a clever twist where the answer sounds like a pun but actually fits the literal definition.
