Expert writing Tips
Best practice
Always ensure subject-verb agreement. "Proof" is a singular noun, so it typically pairs with "was", not "were". Use "were" in hypothetical or subjunctive constructions (e.g., "If proof were to be presented...").
Common error
Avoid using "were" with singular nouns like "proof" unless you're constructing a conditional or subjunctive sentence. Use "proof was" for factual statements.
