One set is used to combine predicate expressions ("e" = and, "a" = inclusive or, "o" = if and only if), and another set is used to combine predicates to make more complex predicates ("ce", "ca", "co"). The sentence "La Kim matma e sadji" means "Kim is a mother and is wise", while "La Kim matma ce sadji vedma" means "Kim is a motherly and wise seller", or "Kim sells in a motherly and wise manner". In the latter sentence, "ce" is used to combine matma and sadji into one predicate which modifies vedma.
