The number of nouns which are used in the genitive case is great so
that it is practically impossible to give an adequate semantic
classification to these nouns.Among them are
proper personal names
common animate nouns
common and proper names of higher animals
parts of the humane body
geographical names
nouns of temporal semantics : a day’s stay ,
his week’s wages
names of organizations , institutions ,
establishments
names of natural phenomena
nouns denoting distances
names of objects of home life :in the room’s
single armchair…
The genitive occurs in a lot of fixed phrases with inanimate nouns:
At a stone’s throw , at arm’s length , for appearance sake , at
one’s wit’s end.
