CHAPTER 10 CONCLUSION 10-1 Dialectal Variation in Aymara The foregoing chapters have examined regional and social variation in Aymara grammatical structure. At this point a return to the questions posed in 1-3.2 is indicated to see what answers may now be given. As has always been supposed, Aymara is clearly one language. Regional and social variation exists but it does not significantly affect intelligibility except when certain utterances are taken out of context, primarily because the phonemic inventory is uniform (except for the velar nasal occurring in only two areas and in very few morphemes) and secondarily because all dialects share a basic set of morphophonemic rules and a basic inventory of morphemes with the same or very similar meanings and similar phonological shapes. Because of the nature of Aymara morphophonemic rules, certain morphemes vary in phonological shape within as well as across dialects. As shown in cross-dialectal and intra-dialectal phonological correspondences and in vowel-dropping or -retaining morphophonemic rules, certain Aymara phonemes are unstable. The most unstable are the sonorants (vowels 716
