Confusing Words

practical vs practicable

These words are often confused because they are closely related and sound similar, but they have distinct meanings and are used in different contexts.

  • practical — practical' means realistic, sensible, or useful in real situations; it describes something that is suitable for actual use or dealing with real problems. For example: She gave practical advice on how to manage stress. A practical person is someone who solves problems in a sensible way.
  • practicable — practicable' means capable of being done or put into practice; it is more formal and technical, focusing on whether something is actually achievable. For example: Is the plan practicable within our budget? Notably, 'practicable' is less common than 'practical'.

Memory rule: Use practical when describing something realistic or sensible; use practicable (more formal) when asking whether something can actually be done. A practical solution is a sensible one; a practicable solution is one that can be carried out.
