What is the meaning of the Latin phrase "cum grano salis"?

FatPanda2408, absolutely, this saying is my philosophy always. It keeps me focused on the real truth and not get swept up in false news, crap on social media and uneducated quips from people who quote the’National Inquirer’

The English word 'salary' also stems from this as soldiers were paid in salt.

Not so sure about the Latin "addito salis grano." First of all, I would not expect the English-sounding verb "addo" or its derivatives, but the imperative form would likely be "adde." The word "grano" is even more suspect; the nominative case is "granum," a second declension word where the accusative (='object') is the same.

jude, Latin. Not Greek!!

veni, vidi vinci. but alas I failed this question. sono scemo
