A collection of sentences developing into a short piece of writing related to one main topic is called a paragraph. Paragraph writing is the foundation of all essay writing, whether the form is expository, persuasive, narrative, or creative.
The most important components of a paragraph include a topic sentence, a supporting sentence and a concluding sentence. The topic sentence is the main idea that acts as a starting point to expand the idea. The supporting sentence supports the topic sentence and develops the main idea by describing it. The concluding sentence summarises a paragraph by providing it a logical closure. It mainly validates the point made in the paragraph.
A paragraph can be narrative, descriptive or persuasive based on the nature of its content. However, whatever form of the paragraph is, there should be unity, variety, coherence and completeness in the ideas weaved in it.
