x_{1} is similar/parallel to x_{2} in property/quantity x_{3} (ka/ni); x_{1} looks/appears like x_{2}.

Also: x_{1} is a likeness/image of x_{2}; x_{1} and x_{2} are alike; similarity and parallel differ primarily in emphasis.

- Property relativizing determiner. {kai'i} introduces a predicate whose first argument slot becomes filled by the property made by taking the bridi in which this {kai'i} appears and putting {ce'u} into the argument slot in which this {kai'i} argument was located. Put formally, "kai'i brodi cu brodu" = "lo ka ce'u brodu cu brodi". Additionally, a {kai'i} term has a rightward logical scope, like quantifiers and adverbials.
