To classify a new expression:
1. Identify the object or act named in the ruling.
2. Look for an added adjective, condition, time, or number.
3. If one exists, state exactly which word or act it limits.
4. Interpret the result within its own context; transferring a condition from another text needs separate justification.
For example, in “Bring an Arabic book on Friday,” the book is the object, “Arabic” qualifies the object, and Friday qualifies the timing.
