Turns out that was actually a thing:

'the line of messianic descent was defined by the French word Sangréal.... In English translation, the definition, Sangréal, became "San Gréal", as in "San" Francisco. When written more fully it was written "Saint Grail", "Saint", of course, relating to "Holy"; and by a natural linguistic process came the more romantically familiar name, "Holy Grail".'

That's just bad etymology. The word/expression Saint Graal in Old French. Saint was translated into English directly as Holy, while Graal was adopted as is morphing into grail. It seems the etymology for graal is likely ultimately Ancient Greek krater, a type of wine bowl.

The 'sang real' (royal bloodline) nonsense was a much later invention (15th century).

Nice to see Dan Brown in our midst.

And here was me thinking Wheel of Time and their "sa'angreals".

episodes are out!

Santo Grial in Spanish, I suspect neural machine translate would have translated their press release into more idiomatic English.

In many languages "saint" and "holy" are the same word.

The automated translation is pretty noticeable.
