Origin & History of “dive”
Old English dȳfan ‘dive’ came from a prehistoric Germanic *dūbjan. this was a derivative of the base *d(e)ub-, a variant of which, *d(e)up-, was the source of English deep and dip. The colloquial use of the noun for a disreputable bar, nightclub, etc, which comes from 1880s America, is probably a reference to someone ‘diving’ out of sight into such an establishment, which was often in a basement.
