Legend
Legendary Story
noun
When people transmit a theory through the ages, it can turn into a legend, or legendary story. Kind of like how the "theory" of King Arthur's sword turned into the legend of Excalibur.
This is a jukugo word, which usually means on'yomi readings from the kanji. You just have to remember that 伝 is read as でん in this case. Just imagine yourself sitting in your den (でん) as you get cozy and listen to this theory about a great legend.
