Expert writing Tips
Best practice
Use "extinct completely" to emphasize that a species, lineage, or other entity has disappeared without any remaining trace. This phrase is particularly effective when you want to remove any ambiguity about the completeness of the extinction.
Common error
Avoid using phrases that are already implicit in the term "extinct". For example, avoid saying something like "absolutely extinct without any survivors", as extinction inherently means there are no survivors. Choose your words carefully to convey the meaning effectively without unnecessary repetition.
