The first element of this name is derived from ag, an uncertain element for which a few possible origins exist. The accepted explanation is that it comes from Proto-Germanic *agjo, which means "sharp, pointed." Because of that, it also means "edge", as in the sharp cutting side of a sword - which is why the meaning of the element has ultimately come to be "sword". See also Anglo-Saxon ecg (in e.g. Egbert) or Old High German ekka (New High German ecke, which means "corner"). Other possibilities for the meaning and origin of ag include: Gothic agan "to fear, to be afraid", Old Norse agi "unrest, agitation", Gothic ahjan "to believe" and Old Norse aka "to do, to act." The second element of this Germanic name is derived from Old High German mâri "famous."
