Expert writing Tips
Best practice
Pair the phrase with verbs like 'awarded', 'moving' or 'developing' to highlight the contrast between an expected fast pace and the actual slow reality.
Common error
Do not describe a tortoise speed as 'sprinting' or 'running'. Since tortoises lumber or crawl, using high-action verbs creates a confusing mental image for the reader. Stick to verbs that match the animal's natural movement.
