A
run-on sentence is a
sentence in which two or more
independent clauses (that is, complete sentences) are joined without appropriate punctuation or conjunction. It is generally considered to be a grammatical error, though it is occasionally used in literature and may be used as a rhetorical device. An example of a run-on is a
comma splice, in which two independent clauses are joined with a comma without an accompanying coordinating conjunction.
[1][2] Some grammarians exclude comma splices from the definition of a run-on sentence
[3], though this does not imply that such usage is acceptable.
