In a way that relates to the cause or origin of something, especially in medicine or science.
The symptoms were analyzed etiologically to determine their underlying causes.
Etiologically → It is formed from "etiology" (from Greek "aitia", meaning cause, and "logia", meaning study) and the suffix "-cal" (meaning pertaining to). The word "etiologically" refers to something that pertains to the study of causes, especially in relation to diseases or conditions.
Think of 'etiology' as the 'study of causes' — and the '-cal' means it relates to that study. So, when you hear 'etiologically', remember it pertains to understanding the causes of something.
