（常指坏的）预兆，兆头 Word OriginMiddle English: from Old French herbergere, from herbergier ‘provide lodging for’, from herberge ‘lodging’, from Old Saxon heriberga ‘shelter for an army, lodging’ (from heri ‘army’ + a Germanic base meaning ‘fortified place’), related to harbour. The term originally denoted a person who provided lodging, later one who went ahead to find lodgings for an army or for a nobleman and his party, hence, a herald (mid 16th cent.).
