What are the basic units of writing: words, sentences and paragraphs, and how do they build meaning?

In one line

Words combine into sentences that express complete thoughts, and related sentences combine into paragraphs that develop one idea; these three are the building blocks of all writing.

Explained simply

Think of a building: bricks (words), walls (sentences) and rooms (paragraphs). Bad bricks make weak walls; walls in random places make useless rooms. Good writing needs all three levels to be right.

Technically, the MU syllabus lists words, sentences and paragraphs as the basic units of writing. Effective writing depends on precise word choice, well-constructed sentences and unified, well-organised paragraphs.

How it works

1. Words: choose precise, simple, familiar and concrete words ('use' not 'utilise'; 'rose by 12 percent' not 'rose a lot'). Avoid jargon for general readers, slang and redundancy.
2. Sentences: a sentence has a subject and a verb and expresses one complete thought. Keep business sentences short (about 15 to 20 words on average), mostly in active voice, with one main idea each. Vary length for readability.
3. Sentence types: simple (one clause), compound (two main clauses joined by and/but/so), complex (a main clause plus a dependent clause such as 'because...').
4. Paragraphs: a group of related sentences developing one main idea, with a topic sentence, supporting sentences and a concluding sentence.
5. Paragraph qualities: unity (one idea), coherence (logical order and links) and adequate length (usually 4 to 8 sentences in reports; shorter in e-mails).

Quick example

Weak: 'The utilisation of the new machine was done by the workers and it was observed by us that output was increased in a very big manner and also the wastage was less.' Better: 'Workers started using the new machine on 1 March. Output rose by 18 percent, and material wastage fell by 5 percent.' Precise words, active voice and two clear sentences make the message stronger.

Common mistakes

• Writing very long sentences joined by 'and' repeatedly.
• Starting a new paragraph for every sentence, or putting several unrelated ideas in one paragraph.
• Using fancy words to impress instead of precise, simple ones.

How MU asks it

Usually part of 'Explain coherence and cohesion in writing' or 'Basic units of writing' (3 to 5 marks). Define each unit, give guidelines for effective words, sentences and paragraphs, and show a short before-and-after example.
