Expert writing Tips
Best practice
In financial or scientific writing, use it to describe data trends that unexpectedly change direction, as it sounds more professional than "flipping" or "switching".
Common error
Avoid using redundant adjectives like "sudden abrupt reversal". Since "reversal" implies a change and "sudden" already covers the speed, adding another synonym creates wordiness without adding meaning.
