You will all say WATER-NERO in Greek. But did you know that NERO-ΝΕΡΟ in Greek has changed?
ΝΗΡΟΝ ΥΔΩΡ-NIRON HYDOR, which meant’fresh water”.
NIRON, by the way, was the root of NEARON, and obviously, NEW.
Gradually, the word HYDOR was redundant and the adjective NIRON became the noun NERO-ΝΕΡΟ.
So, dearest friends, next time you have a drink of water, know that words were not always the same over the years!
