"Rigour" is the British English spelling of "rigor." It refers to the quality of being extremely thorough, careful, and exact in carrying out a task or process. It implies a high standard of precision and attention to detail. Think of the rigour of scientific research or the rigour of a demanding academic program. It often involves strict adherence to rules and procedures. Unlike 'carelessness,' rigour emphasizes diligence and accuracy, like the rigour applied when auditing financial records.
