Best practice
When attempting to emphasize a single occurrence, consider using phrases such as "just once" or "only once" for better impact.
Common error
Don't repeat words unnecessarily. Repeating "once" immediately after itself dilutes the message and makes it appear less professional. Use "once" by itself, or rephrase with alternatives like "a single time".
