Question
What is the right structure for an essay
Answer
A paragraph is a related group of sentences that develops one main idea. Each paragraph in the body of the essay should contain:
  • a topic sentence that states the main or controlling idea
  • supporting sentences to explain and develop the point you’re making
  • evidence from your reading or an example from the subject area that supports your point
  • analysis of the implication/significance/impact of the evidence finished off with a critical conclusion you have drawn from the evidence.
