The nominative and objective cases of a noun have the same form. Thus, there can be no confusion associated in their uses.

Now we can examine the roles of the three case forms.

1.   Nominative Case

The nominative case is used for the subjectOpens in new window of a verb and predicate nounOpens in new window.

For Example:
  • The lawyer argued with plausibility.
  • The girl is a student.

2.   Objective Case

The objective case is used for the objectOpens in new window of a verb or prepositionOpens in new window.

For Example:
  • The farmer built a fence.
  • He drove across the country.

3.   Possessive Case

The possessive case shows ownership or possession. As indicated above in the chart, the possessive case of a noun is marked by the use of an apostrophe ( ).

For Example:
  • This is the teacher’s manuscript.
  • The mob occupied the city's square.

How to Form the Possessive Case

  1. The Possessive Case of a singular noun is frequently formed by adding an ’s to the end of the noun: as, principal’s, doctor’s, lawyer’s, mother’s, bride’s.
  2. The Possessive Case of a plural noun is formed in the following ways:

For singular nouns that end in s or an s–sound (like ce) we usually add only an apostrophe.

For example:

Use of the regular ’s in such instances is not incorrect.

Some Observations of Possessive Case

Observation #1

Observation #2

Some instances of possession indicate a lack of ownership entirely:

  • a day’s work,
  • my year’s salary,
  • the law’s delay.

These phrases mean “the work of a day,” “my salary for a year,” “the delay of the law.”

Observation #3

A noun Opens in new window in the possessive case is usually equivalent to a phrase Opens in new window beginning with of.

For example, we may say:
  • Either “Hardy’s poems” or “the poems of Hardy”;
  • “the governor’s mansion” or “the mansion of the governor”;
  • “the President’s agenda” or “the agenda of the President.”

We would not, however, say

When making such distinctions, one must be guided by one's ear for what sounds correct.

Observation #4

As a general principle only the possessive case is not used with inanimate objects. A phrase with of is used instead.

For example:
  • “the cover of the book” (not “the book’s cover”);
  • “the branches of the tree” (not “the tree’s branches”).

There are exceptions to this rule:
