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

high-level language
HLL

   (HLL) A programming language which provides some level of
   abstraction above assembly language.  These normally use
   statements consisting of English-like keywords such as "FOR",
   "PRINT" or "GOTO", where each statement corresponds to several
   machine language instructions.  It is much easier to program
   in a high-level language than in assembly language though
   the efficiency of execution depends on how good the compiler
   or interpreter is at optimising the program.

   Rarely, the variants "VHLL" and "MLL" are found.

   See also languages of choice, generation.
