Rule1:-
Possessive case is usually used with the name of living things.
eg:- Seeta‘s sister , Boy’s house , Manager’s view etc.
Note: We should not make Possessive Case of Non-living things unless they are personified.
Like it is incorrect to say “Table’s leg” instead we should say “Leg of the table”
But when personified, we can say
eg:- Nature’s beauty, Death’s door etc.
Rule2:-
Possessive case is also used with nouns denoting time, space or weight.
eg:- day’s leave (time), stone’s throw (space), a pound’s weight (weight) etc.

Possessive case is also used with certain dignified objects and familiar phrases.
eg:- the court’s order , the heaven’s will, at his wit’s end
Rule4:-
If else is used with anybody/ somebody/ nobody/ everybody/ anyone/ someone/ none/ everyone the Possessive sign is put to else. Like
- I obey your orders and nobody’s else. (incorrect)

Rule5:-
With compound Noun, Possessive sign is attached only to the last word.
eg:- Sister in law’s (already discussed in noun section)
Rule6:-
When two or more nouns show joint possession, the possessive sign is put to the latter noun only.
eg:- Reena and Geeta’s bed. (here bed of Reena and Geeta is common) but if bed is not common we can say
Reena’s and Geeta’s bed.

Possessive sign is not attached with two consecutive nouns.
- Siya’s brother’s nature is very good. (incorrect)
