To form the possessive case of a singular noun, add an apostrophe and an s.
The possessive case of a noun shows ownership or relationship.

A proper noun ending in s may take only an apostrophe to form the possessive case if the addition of ‘s would make the name awkward to say.
|Texas’ parks||Los Angeles’ weather|
To form the possessive case of a plural noun that does not end in s, add an apostrophe and an s.
