Which word is more common?
Tautology is a more common term than pleonasm in everyday language, as it is often used in academic and technical writing to describe a specific type of redundancy. However, both terms are relatively uncommon in everyday conversation.
What’s the difference in the tone of formality between pleonasm and tautology?
