Today’s name comes from 14th C Germany (Münster, to be precise).
It’s a feminine name found in a Latin document, so we’re hypothesizing the nominative form from the genitive. The Latin nominative isn’t really uncertain — but the underlying name is. The deuterotheme is probably Old Saxon rād, Old High German rāt ‘counsel, advice’, more commonly used in men’s names but occasionally used in women’s names. But the prototheme is eluding us: It’s not clear at all what would give rise to Wey- in German.
Do you have any thoughts? Any other names with the same prototheme? Please share in the comments!
