Why this word is great
AGNAME — [Noun] An appellation over and above the given name and surname. From Latin agnōmen (additional name), with the second element replaced by English name; by surface analysis, ag- (ad-, "to") + name. Unlike "agnomen" (which belongs to Roman tradition) or "nickname" (which carries a casual warmth), an agname is a deliberate, often ceremonial addition—a third axis of identity. It is the weighty "Magnus" appended to a scholar, the resonant "Iron" welded to a warrior, or the whispered "Stormborn" that follows a ruler like a shadow. A name beyond a name, it is the self we are given when the one we are born with is not enough.
