Sentences: Actual sentences, sentence fragments, and run-ons

3.  A complete sentence must:
› Have a subject
 The subject tells who or what does the action.
› Have a predicate
 The predicate contains the verb and tells what
the action is.
 A sentence is a group of words that has
a complete and independent thought.

6.  A sentence fragment is a group of words
that doesn’t state a complete thought.
 Sometimes a fragment is missing a
subject.
 Sometimes a fragment is missing a verb.
 Other times, a fragment has a subject
and a verb, but the thought still isn’t
complete.

10.  The length of a sentence really has
nothing to do with whether a sentence is
a run-on or not. Even a very short
sentence could be a run-on.
 Example:
› Incorrect: The books are heavy don’t carry
them.
› Correct: The books are heavy. Don’t carry
them.

11. Example:
BUFFALO BUFFALO BUFFALO BUFFALO BUFFALO
BUFFALO BUFFALO BUFFALO.
 Buffalo! It's a noun! It's a city! It's a verb (meaning "to
intimidate")! It plays on reduced relative clauses,
different part-of-speech readings of the same word,
and center embedding, all in the same sentence.
Stare at it until you get the following meaning: "Bison
from Buffalo, New York, who are intimidated by other
bison in their community, also happen to intimidate
other bison in their community.“

12.  A run-on is two or more sentences put
together without the correct
punctuation or capitalization.
 A reader cannot tell where one
sentence ends and the next one begins.
