Etymology
Origin of headfirst
Explanation
When you do something headfirst, your head leads the way. For example, a boy might show off by diving headfirst into a chilly lake. The adverb headfirst is useful for describing a dive or a movement that leads with the head. A stormy ocean might fling a swimmer headfirst onto the beach, or an unlucky skier could slide headfirst down a mountain. You can also use headfirst in a more figurative way, to describe something that's done impulsively, or in a foolishly hasty manner: "He plunged headfirst into this new relationship two days after breaking up with his girlfriend."
