2. Run-on sentence
Writing & Everyday · Proofreading and Correction Mark Abbreviations
Correction mark for two or more independent clauses joined without proper punctuation or a conjunction, as in "I was tired I went to bed." The usual fixes are a period, a semicolon, or a comma plus a coordinating conjunction.
Example: Next to "It started raining we went inside," my teacher wrote RO and circled the gap.
Some teachers write "r-o" or "run-on" in full. Strictly, a run-on with no punctuation is a fused sentence, while one joined only by a comma is a comma splice, but many teachers use RO for both. A long sentence is not a run-on if it is correctly punctuated.
