The disturbed water or air currents left behind by a moving vessel, aircraft, or object. Also refers to funeral vigils held before burial ceremonies.
From Old Norse 'vaka' (to be awake, to watch). The water-trail meaning developed from the idea of the 'track' something leaves behind, while the funeral meaning comes from 'watching over' the deceased.
Every moving object leaves a wake - boats create V-shaped water patterns, planes leave contrails, and even walking disturbs the air around us. The physics of wakes reveals hidden turbulence in seemingly smooth motion, much like how our actions leave invisible trails of influence.
