As with all types of grammar, there are rules surrounding the use of the pronoun. Lets take a look at these now.

1) If the pronoun is being used as a subject it is known as a subject pronoun and often appears at the beginning of a sentence, although this is not always the case. An example of this would be She went to the shop.

The words he, I, she, we, whoever, they, it etc are all subject pronouns,

2) Secondly, a subject pronoun can be used if they are renaming the sentence subject, in this case, they always come after to be verbs, these might be verbs such as were, am, are, is, etc. An example of this would be That is she or This is him talking.

3) Another rule is that if the word who is being used as a pronoun to refer to a person, it will take the form of the verb to which that person corresponds, this might sound strange as this rule is not always followed but an example might look like this It is I who am going to town.

4) An object pronouns is used to refer to the object of a sentence. Object pronouns might include the words him, me, her, us, them, etc. An example of this might be Sarah watched her. In this example. her is the object of the verb watched.

5) When a possessive pronoun is used, the use of an apostrophe is never required.

6) When using the pronouns which, that, and who you should use either a singular or plural verb depending on what the pronoun is referring to. For example, look at the following sentence.

• John is one of those men who likes fishing.
• John and Bob are two of these men who like fishing.

You can see that the verb like has been modified to become plural when the pronoun who refers to two people as opposed to one.
