IPA: /rɪˈpʌɡnəntli/
KK: /rɪˈpʌɡnəntli/
In a way that is extremely distasteful or offensive.
The food was served repugnantly, making it hard to eat.
Repugnantly → It is formed from "re-" (meaning against) and "pugnare" (meaning to fight). The suffix "-ly" indicates the manner of the action. Thus, "repugnantly" describes an action done in a manner that fights against or is opposed to something.
Think of acting 'against' ('re-') something in a 'fighting' way ('pugnare') — that's why repugnantly means doing something in a way that is offensive or distasteful.
