See, the issue isn't how you begin to spell "attributable"... but how you stop spelling it.
This qualifies for the coveted Bad Copy award because there's only one brand of people at my place of business that would just keep adding letters to a word until it looks long enough. That brand is SalesGuy (tm). We try to wrangle them with a sophisticated system of handlers and assistants. We even put mittens on their hands so they can't type too easily and get themselves in trouble. But sometimes little gems like this manage to slip out. "Attributalaitable." Solid.
