Introduction
A clause is a group of words containing a subject and a verb.
An independent clause is a complete sentence. It contains the main subject and verb of a sentence.
A dependent clause is not a complete sentence. It must be connected to an independent clause.
An adjective clause is a dependent clause that modifies a noun. It describes, identifies, or gives further information about a noun. (An adjective clause is also called a relative clause.)
Using Subject Pronouns : Who (used for people), Which (used for things).
I thank the woman.
She helped me.
I thank the woman who helped me.
----> I thank the woman = an independent clause.
who helped me = an adjective clause
The adjective clause modifies the noun woman.
The book is mine.
It is on the table.
The book which is on the table is mine.
The man was Mr. Jones
I saw him
The man whom I saw was Mr. Jones
The movie wasn't very good.
We saw it last night.
The movie which we saw last night wasn't very good.
Using Whose
I know the man.
His bicycle was stolen.
I know the man whose bicycle was stolen.
The student writes well.
I read her composition.
The student whose composition I read writes well.
Note : Whose is used to show possession. It carries the same meaning as other possessive pronouns used as adjectives: his, her, its, and their. Like his, her, its and their, whose is connected to a noun :
his bicycle -----> whose bicycle.
her composition -------> whose composition.
