Support ideas with relevant, specific examples

Examples make your writing easier to understand by illustrating points more effectively.

Examples, if used properly, not only help you get higher marks for ‘Task Response’ but also for ‘Coherence’.

When giving examples it is best to put them after your main idea or topic sentence. They can be used in the middle of supporting sentences or they can be used to start a new sentence. There is no rule for where exactly to give examples in essays, logically they would come after your main idea/topic sentence or just after a supporting sentence.

Linking words for giving examples:

  • for example
  • for instance
  • to illustrate this
  • to give a clear example
  • such as
  • namely
  • to illustrate
  • take, for example
