Ac is the vowel sound “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 reversed indicates that things are unstable and not holding faith and honour with what is going on today. What seems like a good idea, turns out to be unsuitable. The presence of mind and dedication just isn’t there.
