Table 2 Capacity for nominalization by khwaam or kaan by semantic type by khwaam while core verbs are nominalized exclusively by kaan. Distribu- tional overlap is found in the semantic margins of the two classes, among HUMAN PROPENSITY and STATE/ACHIEVEMENT terms. The nominalization test therefore clearly does not reliably discover all and only the members of an adjective or verb class, as cited accounts have already indicated. However, it appears to discover an ordered relationship in the distribution of terms from two semantically-defined classes. Namely, it finds that while terms sharing like semantics pattern together, terms from the relatively dissimilar semantic cores of the two sets also contrast in their distribution.
