I don`t seem to understand this usage of “for”, though I suggest what it might mean. In the given example, the unclear combination of words is underlined:
“He saw where, for want of greater activity in offering goods consigned - quicker communication with shippers and buyers, a better working agreement with surrounding commission men - this house, or, rather, its customers, for it had nothing, endured severe losses.”
P.S. Sorry for the long sentence. T_T
Thanks in advance!
