For an OR operation to have a truth value of true only one item in the list need a truth value of true. So, the question "would you like sugar or milk in your coffee" has the answer "yes" if I would like sugar or if I would like milk or if I would like milk and sugar. It only has the answer "no" if I want neither milk nor sugar. Technically correct the answer "yes", but not very useful. If I answer "yes" do I want milk, sugar or both? To over come this, Loglan provides the little word ha to mean which if any.
- ei, tu danza le sakta ha le malna kii letu skafi - Would you like sugar or milk with your coffee?
