IPA: /ˈnɒdə/
KK: /ˈnɑːdər/
A person who moves their head up and down, often to show agreement or to indicate sleepiness.
During the meeting, he was a nodder, agreeing with everything the speaker said.
Nodder → The word 'nodder' is derived from 'nod' (from Old English 'hnoddan', meaning to move the head up and down) and the suffix '-er' (meaning a person who performs an action). A nodder is a person who nods, typically in agreement or acknowledgment.
Think of someone who 'moves their head up and down' — that's what 'nod' means, and the '-er' indicates it's a person doing that action.
