We review each guide for practical usefulness, not just correctness. A good usage guide should give the rule, show the exception, and help a reader make a decision in a real draft.
When examples are available, we connect the article to corpus-backed definitions, synonyms, contrasts, and sentence evidence so the advice is grounded in actual word behavior.
