Avoid four common mistakes:
1. Do not infer the original root solely from surface letters; substitutions can obscure the underlying configuration.
2. Do not confuse permission with obligation; Rules 5 and 7 have different statuses.
3. Do not ignore the specific pattern; Rules 3 and 4 refer to particular plural measures.
4. Do not overlook multiple simultaneous changes; Rule 8 alters both a letter and a preceding vowel.
These checks organize the eight rules into a coherent morphological framework.
