Best practice
Use "completely identical" to emphasize the absolute lack of any difference, especially when precision is critical. For instance, in scientific research, stating that two samples are "completely identical" leaves no room for ambiguity.
Common error
Avoid using "completely identical" when only a high degree of similarity exists. Overstating similarity can mislead readers, especially in contexts where subtle differences matter. Use qualifiers like "nearly identical" or "almost identical" to maintain accuracy.
