Final answer:
Anthropologists refer to 'folktales' as secular, non-historical narratives used primarily for entertainment, which are part of a culture's oral traditions.
Step-by-step explanation:
When an anthropologist uses the term 'folktales,' s/he is referring to a category of verbal narratives that are secular, non-historical, and seen primarily as a source of entertainment. Folktales are part of the oral traditions that have been passed down through generations and are seen in various cultures around the world. These narratives often serve as a means of entertainment but also as a vehicle for preserving culture and providing moral lessons. They are distinguishable from other forms of storytelling such as myths or legends, which may have religious or historical significance.
