Waaaah!
#TIL that [warranty and guarantee], plus [guardian and warden], are actually the same words. No, not just synonyms, but the same French words in different dialects! Back in the days of the Norman conquest of England, Normandy spoke a more Scandinavian flavour of French (because they came from Scandinavia - Norman = North men), which used the w sound when Parisian French used the gu sound.
So William the Conqueror would have been Guillaume in the other dialect.
My mind is blown. What else is being hidden from us!
