korgretro: t₁ controls g₁=t₂ who crosses g₂=k₁ to g₃=k₂ from g₄=k₂.

pargre: c₁=p₁ climbs/clambers/creeps/crawls on barrier/portal c₂=p₂ to destination side p₃ from origin side p₄ using c₄ [limbs/tools]

kai'i (exp!): Property relativizing determiner / unary quantifier constructor. {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.

tsekane: x₁ (linear manifold, vector, etc.) is/lies secant to x₂ (object, surface, curve, manifold, etc.) passing through or toward points/loci x₃ (set of intersected points), by standard/definition/in system x₄.
