folkloristics
Morphology, broadly, is the study of form or structure. Folkloristic morphology, then, is the study of the structure of folklore and fairy tales.
Folkloristic morphology owes its existence to two seminal researchers and theorists: Russian scholar Vladimir Propp and Finnish folklorist Antti Aarne.
