Word Origin & History

shell  (n.)
O.E. sciell, scill, Anglian scell "seashell, eggshell," related to O.E. scealu "shell, husk," from P.Gmc. *skaljo "divide, separate" (cf. W.Fris. skyl "peel, rind," M.L.G. schelle "pod, rind, egg shell," Goth. skalja "tile"), with the notion of "covering that splits off," from PIE base *(s)kel- "to cut, cleave" (cf. O.C.S. skolika "shell," Rus. skala "bark"). Sense of "mere exterior" is from 1652; that of "hollow framework" is from 1791. Meaning "structure for a band or orchestra" is attested from 1938. Military use (1644) was first of hand grenades, in ref. to the metal case in which the gunpowder and shot were mixed; shell shock first recorded 1915. Shell game "a swindle" is from 1890, from a version of three-card monte played with a pea and walnut shells. Shellfish is from O.E. scylfiscas (pl.).

shell  (v.)
1562, "to remove (a nut, etc.) from a shell," from shell (v.). The meaning "to bombard with shells is first attested 1856. To shell out "disburse" (1801) is a fig. use from the image of extracting nuts.

shell   (shěl)  Pronunciation Key 

    1. The usually hard outer covering of certain animals, such as mollusks, insects, and turtles.

    2. The hard outer covering of a bird's egg.

    3. The hard outer covering of a seed, nut, or fruit.

    4. A set of electron orbitals that have nearly the same energy. Electrons in outer shells have greater energy than those in shells closer to the nucleus. Elements in the Periodic Table range from the lightest elements with electrons normally occupying one shell (hydrogen and helium) to the heaviest, with electrons in seven shells (radium and uranium, for instance). See more at atomic spectrum, orbital, subshell. See Note at metal.

    5. Any of the stable states of other particles or collections of particles (such as the nucleons in an atomic nucleus) at a given energy or small range of energies.

shell
1. (Originally from Multics, widely propagated via Unix) The command interpreter used to pass commands to an operating system; so called because it is the part of the operating system that interfaces with the outside world.
The commonest Unix shells are the c shell (csh) and the Bourne shell (sh).
2. (Or "wrapper") Any interface program that mediates access to a special resource or server for convenience, efficiency, or security reasons; for this meaning, the usage is usually "a shell around" whatever.
