Angelology → It is formed from "angel" (from Greek "angelos", meaning messenger) and "-logy" (from Greek "logia", meaning study or discourse). The word refers to the study or discourse about angels, or messengers.
Think of 'angel' as a 'messenger' and '-logy' as the 'study of' — so angelology is the study of messengers.
