[TUHS] Does anybody know the etymology of the term "word" as in collection of bits?

And yet according to Wilner's article "the B1700 appears to
require less than half the memory needed by byte-oriented
systems to represent programs. Comparisons with word-oriented
systems are even more favorable."

Figure 9 shows sample sizes for Cobol, Fortran and RPG II programs
comparing B1700 code sizes with other systems. I was surprised to
see this but didn't look further.

  DESIGN OBJECTIVE

  Burroughs B1700 is a protean attempt to completely vanquish
  procrustean structures, to give 100 percent variability, or
  the appearance of no inherent structure. Without inherent
  structure, any definable language can be efficiently used
  for computing. There are no word sizes or data
  formats—operands may be any shape or size, without loss of
  efficiency; there are no a priori instructions—machine
  operations may be any function, in any form, without loss
  of efficiency; configuration limits, while not totally
  removable, can be made to exist only as points of "graceful
  degradation" of performance; modularity may be increased,
  to allow miniconfigurations and supercomputers using the
  same components.
