📚 When the Sentence Refuses to Stop

Here is a real type of error seen in GCSE papers every year: "She walked into the room it was dark she couldn't see anything the curtains were drawn tight against the afternoon sun she reached for the switch nothing happened."

Every idea is there. None of it is separated. This is a run-on sentence — and it costs marks. Knowing where to stop a sentence is not optional at GCSE. It is the foundation of AO6.
