Common Mistakes When Using Copy That and Roger That
Although these expressions are easy to understand, some mistakes can lead to confusion.
Mistake 1: Assuming They Mean “I Agree”
Neither expression automatically means that you agree with a statement.
– “The new plan is perfect.” — “Copy that.”
This acknowledges the message but does not necessarily express agreement.
If you agree, say “I agree” or “That sounds good.”
Mistake 2: Assuming They Guarantee Action
Acknowledging an instruction does not always mean that you have completed it or promise to complete it.
– “Send the document today.” — “Roger that.”
This confirms receipt, not completion.
To make a clear commitment, say, “Understood. I’ll send it today.”
Mistake 3: Using Them in Every Professional Situation
Both expressions can sound too casual in formal business writing.
Instead of replying to a formal email with “Roger that,” you might write:
“Thank you for the information. I understand.”
Mistake 4: Treating Them as Completely Identical
The phrases overlap in meaning, but their tone and associations differ. “Copy that” is often more neutral, while “roger that” can sound more radio-oriented or playful.
Memory Trick: How to Remember the Difference
Use this simple memory trick:
- Copy that = Copy the message. You received and understood the information.
- Roger that = Received the message. You acknowledge that the message came through.
Think of “copy” as receiving information and “Roger” as a traditional radio acknowledgment.
Both expressions confirm receipt, but neither automatically confirms agreement or action.
