Run-on
SAT glossary · Course Foundations
Definition
Two independent clauses joined by nothing at all. Along with the comma splice it is one of the two illegal ways to run row 1 of the boundary table, which requires a period, semicolon, comma+FANBOYS, colon, or dash.
Run-on in plain English
A run-on sentence happens when two complete, independent sentences get smashed together with absolutely NOTHING connecting them at all — no comma, no conjunction, no punctuation whatsoever. Along with the comma splice (which at least has a comma), this is one of the two illegal ways to combine two independent clauses — legally joining them requires a period, a semicolon, a comma plus a FANBOYS conjunction, a colon, or a dash.
