Confusing Words

therefore vs hence vs consequently vs thus

These conclusion markers all show cause and result, but they suit different sentence styles.

  • therefore — Therefore' introduces a logical result; for example, 'The evidence is unreliable; therefore, the conclusion is weak.'
  • hence — Hence' is a formal way to mean for this reason; for example, 'The sample was incomplete, hence the limited findings.'
  • consequently — Consequently' means as a consequence of what came before; for example, 'The funding was cut; consequently, the program ended.'
  • thus — Thus' can mean in this way or as a result; for example, 'The policy failed and thus weakened public trust.'

Memory rule: Use 'therefore' for clear logic, 'consequently' for consequences, 'hence' for a more formal result and 'thus' for result or method.
