The IF and only IF operator
[edit | edit source]o
[edit | edit source]The little word o means if and only if. We can use it to link predicates together.
Examples
[edit | edit source]- mi godzi o dzoru - I go if and only if I walk
- mi clivi o brute - I am alive if and only if I breath
co, ko, onoi and ico
[edit | edit source]We can extend the basic little word o for connecting arguments ans sentences.
- co - links arguments together
- ko - the forethought equivalent and works with ki
- onoi - the exclusive OR (XOR) operator that means a XOR b but not both
- ico - links sentences
