Combining the two types of clauses makes different types of sentences. Knowing what
type of sentence you have will let you choose the correct form of punctuation to correct
them.
● There are four types of sentences:
o Simple Sentence: A simple sentence has one independent clause.
Ex: The bear likes honey.
We think of simple sentences as short, but as long as you have not added
another clause (which would be another subject and verb) it remains a
simple sentence.
Ex: The black bear likes the honey from the old hollow tree by the
lake.
Adding adjectives such as “black” and “old hollow” as well as prepositional
phrases such as “by the lake”, makes sentences longer without adding an
extra clause.
Ex: The black bear and her cub like honey.
Ex: The black bear likes honey and also eats berries.
Again, to stop being a simple sentence you must have both two subjects
and two verbs. In the sentences above there are either two subjects like
“the black ear and her cub” or two verbs “likes and eats.” Just because you
see an “and,” does not automatically make a sentence a compound
sentence. A simple sentence can have a compound subject or a compound
verb. It only becomes a compound sentence when it has two subjects and
two verbs.
● Compound Sentence: A compound sentence has two independent clauses.
Ex: Hummingbirds drink nectar, and cardinals eat seeds.
Because this sentence has two subjects and two verbs, it consists of two
independent clauses. This means it must be connected by either a comma
and a conjunction or a semicolon.
There are only certain conjunctions which are acceptable to use to connect
two independent clauses. You can remember them with an acronym:
FANBOYS (For, And, Nor, But, Or, Yet, and So). If you use another word
such as because, however, or since your sentence will no longer be a
compound sentence and you run the risk of creating a run-on.
Remember your sentence only requires a comma if you have two
independent clauses.
Ex: The book illustrates the struggle of women in a patriarchal
society and offers a glimpse into a more equal future.
