Relative pronoun

Relative pronouns are pronouns (words which stand for nouns) which relate one meaning to another meaning. The commonest are 'that', 'which', 'who' and 'whose'. 'Where' and 'when' also fit this pattern. In form, most relative pronouns are wh- words, and are the same as interrogative pronouns. The difference lies in how they are used in a sentence.

Relative pronouns often behave like subordinating conjunctions.

'Who' is like the personal pronouns, in that it inflects for case. The forms are:

Subjective	Objective	Determinative Possessive	Independent Possessive
who	whom	whose	whose

• For a common grammatical confusion about the case of 'who', see who - whom.
• For advice on a common spelling error, see who's - whose.
