What’s the correct preposition to use for saying “falling down the stairs” in French? Most of the time I see it written as “tomber dans l’escalier”. It feels a bit weird, though, since I’m rather inclined to translate “dans” as “in”.
Is “tomber dans l’escalier” a fixed expression? Any idea why “dans” is used here, or where it originally came from? Are other prepositions possible, e.g. “tomber de l’escalier” or “tomber sur l’escalier”?
