Ac is the vowel a (ah)
Anglo-Saxon Rune Poem (from ragweedforge.com)
The oak fattens the flesh of pigs for the children of men.
Often it traverses the gannet’s bath,and the ocean proves whether the oak keeps faithin honourable fashion
Ac means oak. It is endurance, stamina and a kind of longevity, much like the oak tree itself. It tells me that I will have the energy to survive the day, or at least I will find that energy and work through it. After the change of things brought about by the action of Inguz earlier this week, I have found a new stability, and with that, new sources of energy, and places to act from, is also part of the sense I have for myself.
