What does hull mean?
A hull is the outer shell of a ship or boat, including the part that forms its shape and helps protect its contents. The term can also refer more generally to an external covering, as in the hull of a seed, nut, or piece of fruit. In shipbuilding and naval writing, the distinction between hull and superstructure is important: the hull is the vessel's body below or around the main working areas, while the superstructure rises above it. As a verb, to hull means to pierce or damage a vessel's hull, often by ramming or some other deliberate impact. The word is useful because it captures both protection and structure: a hull encloses something, gives it a recognizable form, and separates the protected interior from the external environment. In food and botanical contexts, the same image is applied to the inedible or protective layer surrounding a seed or fruit.
The external shell or structural body of a ship, boat, or other vessel; by extension, the outer covering of a fruit, seed, nut, or similar object.
"A layer of barnacles covered the old wooden hull."
The nautical sense is the dominant modern meaning. In botanical and culinary contexts, the word refers to the protective outer layer of a fruit, seed, or nut.
To pierce, damage, or sink a ship or other vessel by striking or ramming its hull.
"The icebreaker carefully hulled the frozen vessel."
This is mainly a technical or literary usage and is less common than the noun.
The plural is formed by adding -s to the noun.
"Several ships' hulls were inspected after the storm."
The word that names a ship's outer shell also describes the shell of a seed, a nut, and many fruits, linking the languages of navigation and nature.

Where does hull come from?
The noun comes through Middle English from Old English hulu, meaning the hull or body of a ship. The Old English word was inherited from Proto-Germanic, with related forms in Dutch hol and German Hülle. The verb developed from the noun's older sense of a ship's body, meaning to strike or pierce that body.
