Use four checks:
1. Which coordinating particle appears?
2. What is the maʿṭūf ʿalayh?
3. Is the first element a subject, object, predicate, adjective, or circumstantial?
4. Does the coordinate follow its grammatical function and case?
In raʾaytu Zaydan wa-Khālidan, identify the first direct object before explaining the second object’s accusative case.
