In future field work a special effort should be
made to obtain more data from monolingual speakers and to
determine whether or not monolingual communities or
communities bilingual in Quechua and Aymara but without
knowledge of Spanish exist.

In addition to the collection of field data, written
sources in libraries and private collections should be con-
sulted, such as materials on Aymara reportedly in the
Universidad Nacional de San Agustin in La Paz and colonial
documents cited by Rivet, especially the works of Bertonio
and Torres Rubio. These, together with sources of
Missionary and Patron Aymara mentioned in 2-4.11, should
be analyzed with the participation of native Aymara-speaking
linguists, annotated, and made available to the Aymara
community.

As for Aymara grammar itself, the following are

suggestions of areas needing further study.

Phonology:
Incidence of the velar nasal in other dialects
Incidence of aspiration and glottalization (are they

decreasing in some dialects?)

Intonation

Morphophonemics:
Morphophonemics of certain Future suffixes and 2>3 I
Conditioning of final vowel dropping on verb sub-

jects and complements, and on verbs
