If it's nullable, then it can't be a boolean.

I'm sure that a subject of such import must have been discussed here before, but if so, I missed it. If it can have more than two values it cannot really be a boolean value, so why call it a nullable bool? Anyone got a better name? I can only come up with truelean or trilean.

No such beast exists, nor shall it ever, (well as long as we're talking C#). It's an instance of the generic nullable struct with an underlying boolean value type. Obviously this doesn't roll of the tongue so well however, maybe nullable representative boolean?

Ah, but null is the absence of a value, so the Boolean actually disappears up the division between its cheeks values.

That may well be true, but I have seen many such references.

Almost. There is Boost.Tribool[^] library. An example of use:
tribool a (true);
tribool b (false);
tribool c (indeterminate);if (indeterminate (a) && !b) do_something();

Yeah, I know. The terminology used in describing nullable types and the misuderstanding it leads to is a bit of a pet hate, as you may well guess from my reply :-)

Surely it should be called 'noolean'?

Closest I can come up with is ternary. There is Balanced Ternary[^], but the "don't care" value is 0 (-1 false, +1 true) though null might better describe a don't "care state" ?

Don't come with that. It reminds me too much of a database where some (censored word) declared boolean columns as varchar(1) and used the letter 'X' as true and null as false. And of course his application failed when there was anything else than 'X' or null in those columns. No doubt that he also would have created a similar chaos if he had known that you can have nullable value types.

In Spanish a "trilero" is a guy who use three cards or pots to hide a small ball to cheat tourists in crowded streets... so avoid that name... if you don't avoid it one of your variables could go to jail... :rolleyes:
