When I think of instructions, I think of the things that actually have to
be decoded by the CPU.  That's why I said 1 to 3 words for the '020 and
'030.  By Motorola's definition, that would be the operation word and
one or two special operand specifiers.  An "instruction" as defined by
Motorola includes those, and any words specifying source and destination
effective address, which can be up to five words each.  1+5+5 = 11,
as someone pointed out earlier.

Others call the operation word the instruction, and therefore say all
instructions are one word.

All three definitions could be considered correct.
