IPA: /æbˈnɔːrməli/
KK: /æbˈnɔrməli/
In a way that is unusual or not normal, often differing from what is expected or typical.
The patient was behaving abnormally, which raised concerns among the doctors.
Abnormally → It is formed from "ab-" (meaning away from) and "normalis" (from Latin, meaning conforming to a standard). The word "abnormally" means deviating from what is considered normal or standard.
Think of something that is 'away from' ('ab-') the 'standard' ('normalis') — that's why abnormally means not normal.
