Expert writing Tips
Best practice
It is particularly effective in biographical introductions where you need to connect a person's name to their field of expertise concisely.
Common error
Do not use 'very' or 'highly' with 'extensively'. Since 'extensively' already denotes a large scale or scope, adding more intensifiers makes the phrase tautological and weakens the professional tone.
