Etymology
The word 'etiology' is a direct borrowing from the Late Latin aetiologia, which itself was adopted from the Greek aitiología. This Greek term is a compound of aitía, meaning "cause" or "responsibility," and -logía, a suffix indicating "the study of." The literal construction, "the study of causes," has remained remarkably consistent in its journey into modern English. While its most common application is in medical contexts concerning the origins of disease, it retains its broader philosophical sense of investigating the causal explanations for any phenomenon, preserving the logical link from its ancient Greek roots.
