197 lateralization and denasalization of /fi/, Morocomarca; final vowel restoration and antepenultimate stress on 2+3 Imperative and certain other person/tense suffixes, La Paz and Sitajara. 4-5 Conclusion Taken as a whole and in spite of its complexities, morphophonemics is a rather stable area of Aymara grammar, contributing to mutual dialect intelligibility (although speakers from La Paz have some difficulty with dialects having extensive stop voicing and frication). Few suf- fixes differ in morphophonemics from one dialect to another, although some are affected by phonologically and syntactically conditioned rules that are dialect specific. Some dialect groups that may be identified by morphophonemic rules are as follows. 4-5.1 Dialects preposing (or restoring) /si/ or /ji/ to sa.fia La Paz (preferred); Juli, Socca, Huancané (less frequent). 4-5.2 Dialects voicing stops after homorganic nasal or palatal lateral before a vowel Salinas (obligatory within a morpheme, permitted across morpheme boundaries under certain conditions; Calacala, Corque, Huancané, Sitajara (optional).
