noun / verb
riposte
rih-POHST/rɪˈpəʊst/
A swift answering attack.
The quick riposte catches the colleague off guard.

Etymology
“Back” and “pledge” formed the idea of promising in return, hence answering. A riposte was a fencing answer—a thrust after parrying—before becoming a sharp verbal counterstroke.
