[rspec-devel] crazy semantic question

[David Chelimsky]

Help please. I'm struggling to find the right word. Here are some  
statements - can you fill in the ???:

The sign of +1 is positive.
The sign of -1 is negative.

The polarity of this magnet is positive.
The polarity of that magnet is negative.

The ??? of the expression "x should y" is positive.
The ??? of the expression "x should not y" is negative.

I've already ruled out 'should-ness' :)

Cheers,
David
