1. Genitive and of-construction

2. Let’s start from the beginning
Nouns may take an -'s ("apostrophe s") or GENITIVE MARKER to indicate possession:      the boy's pen    a spider's web    my girlfriend's brother    John's house
plural form:      the boys' pens    the spiders' webs    the Browns' house
The genitive marker should not be confused with the 's form of contracted verbs, as in John's a good boy (= John is a good boy).

The wheels of the car
