意味

To set out on; to embark on a new venture; to lean forward eagerly; to step in and take action.

A Group 1 (godan) compound verb of 乗る (to ride, to get on) and 出す (to put out, to begin). 乗り出す has two distinct meanings. First, physically, it means to lean or thrust one's body forward — leaning out of a window or leaning in to listen. Second, and more commonly in N1 contexts, it means to embark on or step into an enterprise, investigation, or situation — typically one that requires courage, resources, or a significant decision. Both senses share the idea of moving boldly outward from a position of rest.
