The IF and only IF operator[edit]

o[edit]

The little word o means if and only if. We can use it to link predicates together.

Examples[edit]

  • 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]

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

Examples[edit]

co

  • mi hapci co crano pernu - I am a happy (if and only if smiling) person
  • da nakso le bakso co kuvbao - Someone fix the box if and only chest

ko

  • mi ko hapci ki crano gu pernu - I am a happy (if and only if smiling) person

onoi

  • le crina onoi le solflo gu tetri - the weather is either raining or sunny but not both
  • mi kamla le fusto onoi le livhao - I come to the office or the home but not both
