Rule reminder
Mastery of Italian exceptive clauses requires: (1) Choosing the right connector for context and register. (2) Applying the correct mood (always subjunctive for finite clauses, except 'se non' + indicative). (3) Applying sequence of tenses correctly. (4) Recognizing semantic differences between exceptive, concessive, conditional, and final subordinates. (5) Producing authentic Italian across registers (literary, legal, journalistic, conversational).
