Analysis of a compound sentence
A compound sentence consists of two or more principal clauses joined together by a coordinating conjunction. A compound sentence may also include one or more subordinate clauses.
The coordinating clauses of a compound sentence can be joined by four kinds of coordinating conjunctions.
These conjunctions simply add one clause to another.
He is a fool and you are a bigger fool.
God made the country and man made the town.
He was not only a great politician but also a great orator.
He can’t speak, neither can he hear.
These conjunctions place two alternatives before us.
He is either a fool or a rogue.
You should neither borrow nor lend.
You must obey my instructions, otherwise you will be dismissed.
These conjunctions draw a contrast between two facts.
He is slow but he is steady.
I tried my best, nevertheless I failed.
He is rich, yet he is unhappy.
These conjunctions draw an inference from a statement or fact.
He is diligent, therefore he will succeed.
He may be able to see your point for he is a reasonable man.
He has influence, so he may be able to win the case.

Omission of the conjunction
The conjunction is not always present in a compound sentence.

Omission of the subject
When the clauses have a common subject, we may omit it in the second clause.
The horse neighed and pawed the ground.
Omission of the predicate (when the clauses have a common predicate)
