belabor
Synonym discussion
Sense: verb/1
These verbs all involve speaking negatively, but they do not land the same way. 'Belabor' suggests heavy, repeated criticism that keeps returning to the same weakness or mistake. 'Criticize' is the broad neutral choice and can sound calm or measured. 'Berate' is more openly angry and usually feels direct and personal. 'Scold' often comes from a parent, teacher, or other authority figure correcting someone. 'Attack' is the strongest option and can imply hostility or unfair aggression. A paper may criticize a policy, a parent may scold a child, and callers may belabor a mayor over the same error for days.
Etymology
The word combines the English intensive prefix 'be-' with labor or labour. It first carried the idea of working at or beating at something heavily, and later widened to repeated verbal criticism or overly drawn-out explanation.
