Thanks for that Grandad. Interestingly though wiki says zero comes from the arabic "safira" :
Etymology
The word "zero" came via French zéro from Venetian zero, which (together with cipher) came via Italian zefiro from Arabic صفر, ṣafira = "it was empty", ṣifr = "zero", "nothing".[27]
Also when entering nought into wiki it directs you (thou) to the "zero" page.
I guess we are just going around in circles here (pun intended).
