headfirst

Headfirst is an English term used as an adverb and, less commonly, as an adjective to describe movement or action in which the head leads the way. Literally, it means entering or moving forward with the head first, as when a diver dives headfirst into the water or a swimmer plunges in headfirst. It can also describe figurative actions, such as starting a project or making a decision with strong, unreserved commitment, often implying risk or imprudence, as in going headfirst into a venture.

Etymology and form: The word is a compound of head and first. It is commonly written as headfirst when describing how an action is performed. In some contexts, particularly before a noun, the hyphenated form head-first is preferred, for example “a head-first dive.”

Usage notes: In physical contexts, headfirst describes body orientation during entry into water, snow, or other surfaces. In figurative usage, it conveys enthusiasm or impulsiveness, sometimes with a sense of disregard for caution or consequences. The phrase is versatile across disciplines, including sports commentary, journalism, and everyday speech.

Safety considerations: Headfirst actions carry a notable risk of injury to the neck, spine, and head, especially in shallow water, uneven ground, or restricted spaces. Proper technique, training, and environment are important when attempting activities that involve leading with the head, and some activities discourage headfirst entry altogether.

In culture and language: The two-word form Head First is common in titles and branding, particularly in media and publishing. The phrase appears in various book and media titles and has entered everyday English as an idiomatic expression for approaching tasks with immediate, wholehearted commitment.
