Expert writing Tips

Best practice

Always use "duplicate of" instead of "duplicate for" to ensure grammatical correctness. For example, "Please provide a duplicate of your passport" is correct.

Common error

Avoid using "for" when you mean "of" in the context of creating copies. "Duplicate of" specifies what something is a copy of, whereas "for" indicates purpose or recipient, which doesn't fit the context of replication.
