Apostrophe "s" vs "Of"
I want to know what's the different between the ownership usage:
"He's her mother's son"
"He is the son of her mother"
What's the difference between using "'s " and "of"?
Also, because I don't know exactly how this should be called I call it ownership. But what's its proper name?
Another example is:
"Year of the Dragon"
What's the difference?
