Rule reminder
Key distinction: 'a meno che non' (exceptive) = 'unless' — the main clause is true EXCEPT in the stated condition. 'Sebbene/benché' (concessive) = 'although/even though' — the main clause is true DESPITE the stated condition. Both require the subjunctive, but they express opposite logical relationships.
