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

When I first wrote C code I *assumed* things that were only necessarily
true on the platform I learned on (char=8, short=16, long=32; int=16,
pointer could be either 16 or 32, requiring the addition of the keywords
"near" and "far").
(I'm glad C99 introduced <stdint.h>, but on that platform the only C99
compiler is OpenWatcom.)
