いる connected to a proposition? I'm stuck with the construction of / in the following sentence (Botchan, I) > My translation (excuse my poor English) : > **Being** at the elementary school, it happened that I jumped from the second story of the school, my back broken for about a week. I understand this as if it was a determiner, linked to the word "". But I can't figure out how is linked to the sentence : does somehow introduce ( _confer_ my translation) ?

It is a description of the period of time when this happened. "During the time I was in elementary school". modifies . During which period did this happen? During the period when I was in school.
