From The Jargon File (version 4.4.7, 29 Dec 2003) :

      [orig. Multics techspeak, widely propagated via Unix]
      1. [techspeak] 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.
      2. More generally, 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. This sort of
      program is also called a wrapper.
      3. A skeleton program, created by hand or by another program (like, say, a
      parser generator), which provides the necessary incantations to set up
      some task and the control flow to drive it (the term driver is sometimes
      used synonymously). The user is meant to fill in whatever code is needed to
      get real work done. This usage is common in the AI and Microsoft Windows
      worlds, and confuses Unix hackers.
      Historical note: Apparently, the original Multics shell (sense 1) was so
      called because it was a shell (sense 3); it ran user programs not by
      starting up separate processes, but by dynamically linking the programs
      into its own code, calling them as subroutines, and then dynamically
      de-linking them on return. The VMS command interpreter still does something
      very like this.

From The Free On-line Dictionary of Computing (30 December 2018) :

     1.  (Originally from Multics, widely

     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.
