[vidarh]

To the prefix, it survives widely in Germanic languages to this day in newer forms.

In Norwegian for example, "edel" and "adel" means noble - the former used for objects (a gemstone is an "edelstein" - noble stone; a noble gas is an "edelgass") while the latter refers to the nobility. You'll find one or both or variations in every (I think; certainly most) Germanic language.

We still have names derived from Æthel as well, e.g Ethel, Albert, Adele, Adolf, and others.
