And & Or
There are conjunction, inclusive disjunction and exclusive disjunction in Arka.
They are "o," "az" and "ul."
an siina aples o miik. = I like apricots and apples.
"az" means exclusive disjunction.
aples az miik = an apricot or an apple
"ul" means inclusive disjunction.
aples ul miik = an apricot and/or an apple.
De Morgan's Laws
○∨ indicates exclusive disjunction.
tu et har o gek = red and round = p∧q
tu et har ul gek = red and/or round = p∨q
tu et har az gek = red or round = p○∨q
tu de har o gek = tu et en har ul en gek = ￢(p∧q)＝￢p∨￢q
tu de har ul gek = tu et en har o en gek = ￢(p∨q)＝￢p∧￢q
tu de har az gek = ￢(p○∨q)
If you negate "tu et har o gek" (This is red and round), you will get "tu de har ul gek" (This is not red and/or round)
You have to change "o" into "ul."
Or Other
aples az miik az alt = an apricot or an apple or other
aples ul miik ul alt = an apricot and/or an apple and/or or other
Whether
You can mean whether with "az."
non en ser nan siina la az. = I don't know whether I like him or not.
