Expert writing Tips
Best practice
When referring to a software extension, use "turn off the extension" or "disable the extension" for clarity. For physical extensions, consider "extension of" or rephrase the sentence for better readability.
Common error
Avoid using "extension off" to describe something that is a continuation or part of something else. "Off" typically implies disconnection or removal, so phrases like "extension of" or "branching from" are more appropriate in those contexts.
