To understand how to form the possessive case of nouns in English, we follow specific rules related to adding apostrophes:
For singular nouns , we generally add an apostrophe followed by an 's' ('s) to show possession. For the given examples:
The car of my father becomes my father’s car .
The bag of my sister becomes my sister’s bag .
The pet of Ahmed becomes Ahmed’s pet .
The tail of the monkey becomes the monkey’s tail .
The feathers of the peacock become the peacock’s feathers .
For plural nouns that end with an 's', we simply add an apostrophe (') at the end of the word:
The cycles of the postmen becomes the postmen’s cycles .
The kits of the players becomes the players’ kits .
The croaking of the frogs becomes the frogs’ croaking .
When a plural noun does not end in 's', we add 's to form the possessive:
The computers of the men becomes the men’s computers .
These rules help in identifying and correctly using the possessive form to denote ownership or relationships between nouns.
