IPA: /ˌheɪɡiˈɒlədʒi/
KK: /hæɡiˈɑlədʒi/
A type of literature that focuses on the lives and writings of saints or other venerated figures.
The hagiology of the early church provides insight into the lives of its most revered saints.
Hagiology is formed from "hagio-" (from Greek "hagios", meaning holy or sacred) and "-logy" (from Greek "logia", meaning study or discourse). The word refers to the study of holy persons or saints.
Think of 'holy' ('hagio-') and 'study' ('-logy') to remember that hagiology is the study of holy figures.
