What is a paragraph? A paragraph is a collection of related sentences dealing with a single topic. Learning to write good paragraphs will help you as a writer stay on track during your drafting and revision stages. Good paragraphing also greatly assists your readers in following a piece of writing.

Nowadays, most people leave a line space between paragraphs, without indenting the first line: this is probably the easiest thing to do.
