Questions & Answers about Le casque est obligatoire en spéléologie, à moins de rester dehors.
Why do we use à moins de + infinitive here instead of à moins que?
We use à moins de + infinitive because this is a general statement where the implied subject (people going caving) is the same for both the main rule and the exception. You generally use à moins que followed by the subjunctive when the second clause introduces a new, specific subject. For example: Le casque est obligatoire, à moins que tu ne restes dehors (The helmet is mandatory, unless you stay outside).
Why use the preposition en for en spéléologie instead of dans la?
In French, en is used before feminine nouns that represent a discipline, science, or sport to mean "in the field of." You will see this often with fields of study like en médecine (in medicine) or en informatique (in computer science). Using dans la would sound awkwardly literal, as if you were physically stepping inside the concept of caving.
Just to be sure, does rester mean "to rest" here?
No, rester is a classic false friend! It means "to stay" or "to remain." That is why rester dehors translates to "stay outside." If you actually wanted to say "to rest" after a long day of caving, you would use the reflexive verb se reposer.
Could I say à l'extérieur instead of dehors?
