Coherence of a paragraph is important to maintain continuity.  

This can be accomplished by making use of sentence connectors, such as introductory words or phrases, as follow:

  • In addition, ...;
  • Furthermore, ...;
  • Moreover, ...;
  • On top of that, ...;
  • Consequently, ...;
  • As a result, ...;
  • Hence, ...;
  • therefore, ...;
  • On the contrary,...;
  • Nevertheless, ...;
  • Conversely, ...;
  • Otherwise, ...
  • For instance, ...;
  • For example,...;
  • Take the case of...
  • Likewise, ...;
  • Similarly, ...;
  • To conclude, ...:
  • In short, ...
  • Once, ...;
  • Still, ...;
  • Later, ...;
  • Finally, ...;
  • Indeed, ...;
  • In fact, ...;

The idea here is to break the topic into smaller units , each of which is used as a basis for your paragraph.

The last sentence in a paragraph is the concluding sentence of the paragraph. Use different words to restate the idea as introduced by the topic sentence in this concluding sentence – a summary of what has been discussed.
