In the following sentence (in the short story I'm reading) :
Il passa devant moi, pris les marches.
I'm having trouble understanding the word "pris". My best guess for translating this sentence is "He passed in front of me, taking the stairs". But I would have expected "pris" to be instead a present particple of prendre, for this translation.
wordreference says that "pris" is either a past participle of prendre, or it's an adjective. I can't see how to make sense of "pris" if it was an adjective (what noun would it be modifying?), but I also don't understand how it is being used as a past participle.
1. What is "pris"? Is it a past participle? How is "pris" being used in this sentence? 2. What does this sentence mean?
