The word "harbinger" traces back to medieval logistics. Originally, a harbinger was a royal officer sent ahead to secure lodging (harborage) for a traveling group, especially armies or nobles. Over time, the term evolved metaphorically to mean any precursor or sign of what’s to come, reflecting the idea of "preparing the way" for future events. The Germanic root heriberga (shelter) highlights its practical origins in travel and hospitality.
