Best practice
Avoid overuse in formal academic writing; consider more precise terms like "empirical evidence" or "case study" for increased rigor.
Common error
Don't use "living proof" to describe abstract concepts or situations where tangible evidence is lacking. Ensure the subject is a concrete example that directly supports the claim, for example, instead of saying "The theory is living proof of the concept," say "The successful experiment is "tangible evidence" of the concept".
