The English word ‘rich’ is related to ‘regal’ and ‘royal’.

‘Rich’ derives from a Proto-Germanic borrowing of *rīxs, the Proto-Celtic cognate of Latin ‘rēx’, meaning “king”.

The meaning “wealthy” evolved from “powerful; kingly”.

Latin ‘rēx’, in turn, is the ancestor of Spanish ‘rey’ and French ‘roi’. Via French, ‘regal’ and ‘royal’ come from ‘rēgālis’, a derivative of ‘rēx’.

@yvanspijk funnily, Turkish languages have the -bek suffix in names with the same meaning as -rich. (I translated Henning into Kyrgyz as Üibek.)
@yvanspijk did the political meaning of German "Reich" as an "empire" develop in lock step with reich as in rich? I think that AHD rihhi was the political word? Probably wealth without a Reich is a newer spin off?
@pjakobs The political word already existed in Proto-Germanic, the noun *rīkijan, although the evolution of the meanings "rulership; kingdom" into "empire" happened later.
