612 is reflected in these semantic features, as is to be ex- pected of such an important linguistic postulate in the language. Investigation of other semantic features of Aymara has only just begun. Among those tentatively identi- fied so far, in addition to human/nonhuman, are distinctions of animate/inanimate (or moving/nonmoving), animal/nonanimal, plant/nonplant, and humanly processed/unprocessed. There is apparently no set hierarchy of features; rather, they cut across each other. Nonhuman may subsume animate and inanimate, but animate may subsume human, animal, and moving natural phenomena such as fire, sunlight, hail, and clouds. Inanimate may subsume plant, humanly processed agricultural products or manufactures, or nonprocessed non- moving matter such as rock, earth, or places. Human may subsume a distinction of human persons vs. human body parts or secretions (e. g. blood, urine) and conditions affecting them (e. g. cold, sunlight). Illustrations of these dis- tinctions are given below. They remain working categories pending further refinement as Aymara semantic studies pro- ceed. One instance in which the human/nonhuman distinction is overriding with respect to verb stems and themes concerns the behavior of the nominalizing suffix -fia (7-4.21.2). This suffix is unmarked for human/nonhuman on verb roots. All roots may take it, regardless of the semantics of their
