Etymology: The word is an alternative spelling of "aetiology," and its history is one of a Greek word that meant "giving a cause" before it came to name a whole field of study. The Greek "aitia" meant "cause" or "responsibility," and "logos" was "word," "reason," or "account," so "aitiologia" literally meant an account of causes. Ancient Greek writers used it to explain why things were the way they were, a sense that survived into Latin as "aetiologia" and then into English. The word is also a compound built from familiar parts: "aetio-," from the Greek root for cause, plus "-logy," the suffix for a branch of knowledge. English borrowed it directly from Latin, so the spelling "aetiology" follows Latin letters, while "aitiology" is the same word with the Greek-influenced "i" spelling.
