Therefore means for that reason and signals a conclusion based on what came before.

The idea

Use a separate sentence, a semicolon, or a suitable conjunction: The room is unavailable; therefore, we need another place. It can also follow an auxiliary: may therefore need checking.

Examples

  • The room is unavailable; therefore, we need another place.
  • The road is closed, and therefore the bus takes a different route.
  • The shop opens at ten. Therefore, we cannot enter at nine.
  • The team found an error and therefore revised the plan.
  • The tickets sold out; therefore, they chose another date.
  • The map is old; the route may therefore need checking.

Watch out

Therefore signals the writer’s reasoning; the connection still needs evidence and does not automatically make the conclusion true.
