Expert writing Tips
Best practice
Use "in practice" to clearly contrast a theoretical plan or expectation with the actual outcome or reality of a situation. This helps highlight discrepancies or unexpected results.
Common error
Avoid using "in practice" without establishing a theoretical or planned scenario first. Ensure there's a clear contrast between what was intended or expected and what actually happened. For example, instead of saying "In practice, the system failed", provide the context: "The system was designed to handle 1000 users; however, in practice, it crashed with just 500".
