Reflexive pronouns




Definition: We use the reflexive pronouns to indicate that the person who realizes the action of the verb is the same person who receives the action. Reflexive pronouns are identical in form to intensive pronouns.

 SubjectReflexive
SingularI
You
He
She
It
myself
yourself
himself
herself
itself
PluralWe
You
They
ourselves
yourselves
themselves

For example:
  • I cut my hair myself.
    * In this example "I" does the action of cutting the hair and at the same time "I" gets the action of the hair being cut.

  • We defended ourselves brilliantly. 
    * In this example the reflexive pronoun "ourselves" refers back to the subject of the sentence.

  • John talks to himself when he is nervous.
    * In this example "Himself" refers to John.

Reflexive pronouns always act as objects not subjects, and they require an interaction between the subject and an object.
For example:
  • Because she was not hungry when the cake was served, Ellen saved herself a piece.
    * In the independent clause, "Ellen" is the subject and "herself" is a reflexive pronoun acting as the indirect object. This sentence is grammatically correct.

  • Jhon and myself are going to the movie.
    * In this sentence, "Jhon" and "myself" are the subjects. Reflexive pronouns cannot be subjects. This sentence is grammatically incorrect.

Care must be taken to identify whether the noun is singular or plural and choose the pronoun accordingly.
For example:
  • Nor is she shy about giving herself credit for it.
  • We gave ourselves a second chance to complete the course.
  • Did they lock themselves out of the house again?
  • Give yourselves a pat on the back for a job well done.

Note: The reflexive pronoun can also be used to give more emphasis to the subject or object (intensive pronoun).
For example: 
  • I did it myself. 
    * I want to emphasise the fact that I did it.

Examples:
  • He washed himself.
  • She looked at herself in the mirror.
  • Diabetics give themselves insulin shots several times a day.
  • After the party, I asked myself why I had faxed invitations to everyone in my office building.
  • Richard usually remembered to send a copy of his e-mail to himself.

Present, Past and Future tenses

Use the Simple Present to express the idea that an action is repeated or usual. The action can be a habit, a hobby, a daily event, a scheduled event or something that often happens. It can also be something a person often forgets or usually does not do.

Use the Simple Past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind.

Simple Future has two different forms in English: "will" and "be going to." Although the two forms can sometimes be used interchangeably, they often express two very different meanings. These different meanings might seem too abstract at first, but with time and practice, the differences will become clear. Both "will" and "be going to" refer to a specific time in the future.

Subject verb Agreement

Basic Rule

The basic rule states that a singular subject takes a singular verb, while a plural subject takes a plural verb.
NOTE: The trick is in knowing whether the subject is singular or plural. The next trick is recognizing a singular or plural verb.
Hint: Verbs do not form their plurals by adding an s as nouns do. In order to determine which verb is singular and which one is plural, think of which verb you would use with he or she and which verb you would use with they.
Example:
talks, talk

Which one is the singular form?
Which word would you use with he?
We say, "He talks." Therefore, talks is singular.
We say, "They talk." Therefore, talk is plural.

Singular and Plural Possessive nouns



A possessive noun tells us who (or what) owns or has something. Possessives answer the question "Whose?" Study the following rule and examples and then try the practice exercises.


Rule 1: to make a singular word possessive, just add 's
    Tom => Tom's fault
    Kathy => Kathy's job
    the doctor => the doctor's coat
    the Jones => the Jones's house



Possessive nouns (plural)

Plural nouns follow slightly different rules for making them possessive. Study the following rules and then complete the practice exercises.


Rule 1: add ' to a regular plural noun which ends in s
    dogs => dogs' leashes
    teachers => teachers' desks

Rule 2: if the plural noun does not end in s, add 's
    geese => geese's pond
    children => children's rollerblades
