When describing physical markings, ensure clarity about what is being marked and the method of marking. For example, instead of simply saying "items were marked on their surface", specify what the marks indicate, such as "items were marked on their surface with expiration dates".
Common error
Avoid using "marked on their" without specifying the context or purpose of the marking. For instance, instead of saying "mistakes were marked on their papers", clarify the type of marks and their significance: "errors were marked on their papers with red ink to indicate areas for improvement".
