- Seul compte le fait que je n’ai pas le droit d’échouer ! Je sais que la tâche est immense, mais elle en vaut la peine.
I think it would be heavy to form this sentence with the subject "le fait" with the start of the sentence. Is this why the inversion is used?
Also, I think that an adverb or a preposition is always used a the start of a sentence in an inverted sentence.
- Derrière ... se cache (the subject).
What is the rule for determining when the inversion is OK to use or not?
