Fiducia TogetherSentence forms
Simple, compound, complex and minor sentences, and what each does.
Please note: This page explains a word or a process in education. It is general information about the system, the law and the guidance in England — not advice about your child, your school or your exam. If a decision is going against you, get advice from one of the free services we link to before you agree to anything or miss a deadline. If you are revising, check your own exam board's specification: boards word things differently and yours is the one that marks you.
What it is
A simple sentence has one clause. A compound sentence joins two with a coordinating conjunction. A complex sentence has a main clause and one or more subordinate clauses. A minor sentence is deliberately incomplete.
Where it applies
English Language reading and writing.
How it works
Length and structure control pace. A run of long complex sentences slows a passage; a short simple one after them lands hard.
A subordinate clause placed first delays the main point, which creates suspense.
How to use it in your work
When analysing, comment on the EFFECT of the form, not the label. "The single-word minor sentence isolates the moment."
In your own writing, vary deliberately and use a short sentence at the point you want to land.
Avoid analysing sentence length without an effect. "The writer uses a short sentence" is not a point.
Where to get help
Your teacher, your board's mark scheme and its examiners' reports — those say exactly what separates the bands, and they are free.
Revise this with a song
These are ours. We write revision songs because a lot of people remember a tune when they cannot remember a page, and because revising out loud in the kitchen beats staring at a highlighter.
