Expert writing Tips
Best practice
When describing a temporary inability to see due to external factors (e.g., darkness, fog), "could not see" is appropriate. However, for permanent visual impairment, consider using phrases like "was blind" or "had impaired vision".
Common error
Avoid using "could not see" when you mean "could not understand" or "could not predict". While metaphorical extensions are common, ensure the context maintains a clear connection to visual perception. For abstract concepts consider alternatives like "could not understand" or "could not foresee".
