Letter: F
Fehu means cattle, If you keep in mind that the runic alfabet is about 5000 years old, you look at the meaning that it had in that time. Cattle was something that you could pay with like money. It stands for wealth, particularly movable wealth so not a house or a piece of land. It is the rune of prosperity and manifestation. It can be worn as a good luck symbol.
Fehu is associated with Freya, The Norse godess of love, battle and death.
