Pronouns : Common Errors - 2

1. (W) I heard all what she said.

(R) I heard all that she said. (or)

I heard what she said.

Note:- The relative "what", "that which" or "those which", and has therefore no antecedent. Guard against the misuse of what with an antecedent.
(The term "antecedent" means the noun or the pronoun to which a later pronoun refers)

2. (W) The dog has it's bone.

(R) The dog has its bone.

3. (W) Its a long way home.

(R) It's a long way home.

Note:- Understanding the use of it's and its is simply a matter of remembering that
(1)It's is two words - it and is, and
(2)Its is a possessive pronoun.

4. (W) If I were him, I should not go.

(R) If I were he, I should not go.

Note:- Predicative pronouns must agree in case with the word to which they refer.

5. (W) This is one of the most remarkable events that has happened this century.

(R) This is one of the most remarkable events that have happened this century.

Note:- The agreement of the Relative Pronoun with its Antecedent: several difficulties arise in connection with this rule of syntax. A Relative pronoun agrees in number and person with its antecedent, but takes its case from its function in its own clause. In the above sentence, "has" must be changed to "have" to agree with its subject "that" which is plural because its antecedent ("events", and not on") is plural.
