ES5000 Chap.7 Paragraph Unity and Coherence
Paragraph Unity and Coherence
What an academic paragraph contains
The Week 4 handout lists four features expected in an expository or argumentative paragraph: a topic sentence, supporting sentences, proper referencing of sources and a concluding sentence.
It then insists that these parts be organised coherently, and gives four devices for doing so: linking words or phrases, given-to-new progression, repetition of keywords or synonyms, and associated words from the same field.
Unity: one idea, fully developed
A paragraph has unity when it works out one idea in full and connects that idea to the paper as a whole.
The handout's guidance reads like a revision checklist. Build the paragraph around one major idea, express it in the topic sentence, and make its relation to the paper's thesis explicit rather than trusting readers to see it. Support it with details, move details that approach the topic from a different angle into separate paragraphs, and cut sentences that do not support the idea, or widen the idea to include them.
The handout contrasts a paragraph that opens with a quotation and drifts between topics with a revised one built on a tight topic sentence.
Coherence: order and signposts
Coherence comes from ordering sentences logically and linking them with clear transitions.
The handout offers five orders: chronological sequence, modified chronology that states a major idea early and then supplies background, spatial position, a conversation between experts, and a logical form of argument. Once the order is fixed, transitions act as signposts for the reader.
Where the course uses this
These ideas return in Week 6, when the cause-effect paragraphs are drafted and reviewed.
The peer review checklist asks about topic sentences with a clear claim and controlling idea, supporting sentences that develop them, and unity, coherence and cohesion, including given-to-new progression, connective devices, this plus a summary word, and clear pronouns. A coherence exercise gives shuffled sentences to put back in order.

Key terms
- Topic Sentence
- The sentence that states a paragraph's claim and its controlling idea, usually at the start.
- Controlling Idea
- The part of a topic sentence that limits what the paragraph will discuss.
- Paragraph Unity
- The quality of developing one main idea throughout a paragraph and linking it to the paper's thesis.
- Paragraph Coherence
- The quality of sentences following a logical order joined by clear transitions.
- Given-to-new Progression
- Beginning a sentence with known information and ending it with new information.
- Transitional Signpost
- A linking word or phrase that shows the reader how one sentence relates to the next.
Paragraph Unity and Coherence FAQ
What is the difference between unity and coherence?
Unity is about content: every sentence supports the paragraph's single main idea. Coherence is about connection: the sentences follow a logical order and are joined by transitions a reader can follow. A paragraph can be unified yet incoherent if its relevant sentences are badly ordered.
Can a paragraph start with a quotation?
It can, but the handout shows why it usually fails: a paragraph that opens with someone else's words often never states its own idea. Put your claim in the topic sentence and bring the quotation in as support afterwards.
How do I choose the order for my supporting sentences?
Match the order to the content. Events suit chronological order, description suits spatial order, a debate suits a conversation between experts, and a proof suits logical order. Decide the order before drafting so that the transitions follow from it rather than being added later.
What does this plus a summary word mean?
It means pointing back to a previous idea with this and a noun that names it, such as this increase or this policy. It carries given information into the next sentence and avoids an ambiguous this standing alone, which the peer review checklist lists as a cohesion device.
Assessment move
Before submitting any paragraph, read only its topic sentence and concluding sentence together. If the pair does not make sense as a two-sentence summary of the paragraph, the paragraph has drifted and needs revising before anything else.
