Appendix 3: Academic Sentences – Simple to Complex

When writing academic or scientific research papers, it is important to use a combination of simple, compound, and complex sentences to express ideas and arguments clearly, precisely, and logically. As a general rule:

  • Do not write too many simple sentences. This makes it difficult for the reader to follow the logic of the argument.
  • Do not write overly long, complex sentences that express too many ideas. This makes the writer’s arguments confusing and unclear to the reader.

Basic rules

A complete sentence starts with a capital letter and ends with a period, question mark or exclamation mark.
