You've got a good point. I don't know what would be involved, nor how practical it would be, but putting something like Google's "do you mean foo?" in Super Search might be helpful. If that's impractical, then maybe a sort of Wiki-like "disambiguation page" for the more common mistakes. Ternary/Trinary would be a good one. Can't think of anything else right off, but surely there are plenty more.

OTOH, I suppose that if I did enter something about trinary operators, I'd encounter questions using that term, and see the corrections offered by the Monks - so I'm not sure that it would be worthwhile to go to the trouble of making such changes. I wonder whether this is a big enough problem to "fix" anything.
