Comma splice Comma splice In English grammar, a comma splice or comma fault is the use of a comma to join two independent clauses. For example: The comma splice is sometimes used in literary writing to convey a particular mood of informality. Otherwise, it is usually considered an error in English writing style. Some authorities on English usage consider comma splices appropriate in limited situations, such as informal writing or with short similar phrases. Comma splices are rare in most published writing but are common among inexperienced writers of English. The original 1918 edition of "The Elements of Style" by William Strunk
