An unextended sentence contains two main positions of the basic pattern, that of the subject and tlie
predicate.
Mary laughed.
Mary is a doctor.
Mary is happy.
An extended sentence may contain various optional elements (including attributes, certain kinds of

John ran quickly to me.
My friend John is a very kind student.
Mary laughed heartily at the joke.

John learned French. (the meaning of learned is incomplete without the object French)
John gives Mary his books. (the meaning of gives Mary conveys different meaning without the object
his books)
John lives in London, (the meaning of lives is incomplete without an adverbial of place)
One-member sentences
