A topic sentence is a sentence that expresses the main idea of a paragraph. It summarizes the content of the paragraph and helps the reader understand the key point that will be discussed.
Repetition is one way to develop a paragraph to make the writing easy to understand and helps the reader to keep the central idea in mind. This is done by repeating key words throughout the paragraph. The repeating of sentence structures is also helpful for paragraph development.
detail means you have to write all necessary information about the subject discuss in the paragraph or sentence for them to understand better about the subject matter.
The most important aspect of paragraph development is that it keeps the reader reading. If a story is worded and formed poorly, no one will want to read it. Good paragraph development will make the story easier to understand as well.
the first sentence of the paragraph is called the topic sentence which should describe most of the paragraph for the reader to understand. The topic sentence is usually the first sentence of a paragraph. It makes a statement (about a topic) and the rest of the paragraph explains the topic sentence or gives examples of the topic sentence. The second sentence of a paragraph can sometimes be the topic sentence. Sometimes it is called a summary sentence.
