The term "word" exists in computing to denote a grouping of Binary bits that comprise an instruction.

Yes but you didn't say word, you said "programming word". What's one of those?

bit, nibble, byte, word, double-word...no programming word in that bunch. 'Word' can be used to signify a data type or a machine/compiler specific number of bits, generally the same as the instruction length(but not always). When I first read the post I had assumed he meant the latter.
