There is a central idea in all the sentences above, and all of
them are grammatically complete and independent.
2) Compound sentences
A compound sentence consists of two independent clauses that are connected
by a coordinating conjunction or a semi-colon. However, both sentences are
independent and complete in meaning. If coordinating conjunctions link the
two independent clauses, using a “
comma
” is necessary. There are seven
coordinating conjunctions:
for, and, nor, but, or, yet, so (fanboys)
The following examples show how they form compound structures.
For example
He likes coffee
,
but 
his sister prefers tea.
She enjoys doing sports
, so
she goes jogging every day.
We did not go to the park
; 
we went to the movies instead.
He missed her so much
,
yet 
he did not call her.
He loves fruits
, and 
his favorite fruit is apple.
