Journey

The term originates from the Greek 'taxis', referring to the arrangement of soldiers in a phalanx. In medicine, it historically referred to the physical repositioning of a hernia. In biology, it became a suffix-forming root for describing directional movement (taxis) toward or away from a source (e.g., phototaxis).
