Question

is the following sentence complete or a run-on?
julie stopped for coffee on her way to work,
she needed caffeine.
complete
run-on

Explanation:

The given text contains two independent clauses ("Julie stopped for coffee on her way to work" and "she needed caffeine") joined only by a comma, which is a comma splice—a type of run-on sentence. A complete sentence has only one independent clause (or properly joined clauses with a conjunction or correct punctuation like a semicolon).

Answer:

run-on
