Erilaz is a Migration period Proto-Norse word attested on various Elder Futhark inscriptions, which has often been interpreted to mean "magician" or "rune master", viz. one who is capable of writing runes to magical effect. However, as Mees (2003) has shown, the word is an ablaut variant of earl, and is also thought to be linguistically related to the name of the tribe of the Heruli, so it is probably merely an old Germanic military title (see etymology below).
This word is likeliest the Proto-Germanic ancestor of Anglo-Saxon eorl (Modern English earl) and its relatives, meaning "man, warrior, noble". The word erilaz is likely a derivative of *erǭ sb.f. "fight, battle", thus the interpretation "one who fights, warrior", though it has also been connected to *arô sb.m. "eagle".
Historical instances:
The Lindholm "amulet" (DR 261 $U) is a bone piece found in Skåne, dated to the 2nd to 4th centuries. The inscription contains the word Erilaz.
I WANNA GO TO HEAVEN JERRY WALLACE
Don't know much about heaven.... But, the stories..I've been told... Say the gates are bright and pearly... and the streets are paved with gold....
Don't know much about.. angels...You're the first I've run into.... But, I wanna go to heaven... If it's anything like you...
( Don't know much about Halo's... Never set upon a throne... But, I swear I've been in heaven.. Since the day you came along..
Don't know much about forever... You're the only thing in view... Yes, I wanna go to heaven... If it's anything like you...)
Break... Repeat chorus: ( )
