Expert writing Tips
Best practice
In formal academic writing, consider replacing 'completely' with 'entirely' or 'wholly' for a more sophisticated tone.
Common error
Avoid using "that's completely true" alongside other redundant qualifiers like 'factually' or 'actually' (e.g. 'that's actually completely true'), as the adverb 'completely' already provides maximum intensity.
