Heil!

> galauben: faith - related to German 'glauben'

I made a typo here; the Gothic form is 'galaubein'.

As a bonus, since a typo-correction is not really
enough of an occasion for a whole new post, I present
to you the declension of the Gothic strong (a-stem)
noun compared with the (early) Old Norse version of
the same, which is hopefully familiar to many of you.

nom. fisks fiskR
acc. fisk fisk
dat. fiska fiski
gen. fiskis fisks

nom. fiskos fiskaR
acc. fiskans fiska
dat. fiskam fiskum
gen. fiske fiska

As you can see the Norse 'R' consonant is 's' in Gothic.

Kveðja,
