Final answer:
The tradition passed down by word of mouth is called oral tradition. It is important to note that oral traditions can be just as accurate as written history and play a valuable role in understanding history and cultural identity.
Step-by-step explanation:
It refers to the transmission of information, stories, and cultural practices from one generation to another through spoken words, stories, and songs rather than through written records.
Examples of oral traditions can be found in various cultures and religions. For instance, many indigenous peoples, such as Indigenous Australian peoples, rely on oral traditions to pass down their history, myths, and rituals. Even in religions that primarily rely on written texts, such as Islam, Christianity, and Judaism, there are significant oral components in the practice of these faiths.
