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.
