rightness

oikeudenmukaisuus

sopivuus

oikeellisuus puhekieltä The characteristic of being right; correctness.
puhekieltä The result or product of being right; something correct.
The property of being on, or moving toward, the right.
1996, Robert Cummins, Representations, Targets, and Attitudes (page 105)

I think we are inclined to think the leftness and rightness can be represented because there is a word in our language that means left, and another that means right, and we understand those words.
