719 Aymara dialects fall into two major groups: (1) a northern group of dialects located on or near Lake Titicaca and including La Paz (the city and the department), and (2) a southern group at a greater distance from the lake in the departments of Oruro and Potosi. The intermediate dialects of Celacoa and Sitajara in southern Peru southwest of Lake Titicaca share some features with the northern and some with the southern group; Calacoa has more northern features, and Sitajara, more southern ones. (Figure 10-1 is a preliminary attempt to distinguish the three dialect areas.) Apart from the division into northern, southern, and intermediate dialects, there is a distinction between a central group of La Paz dialects and those on the periphery of La Paz influence, whether to the north, south, or west. (It may be that certain dialects located in La Paz depart- ment north and east of the capital may also have to be designated as peripheral when more is known about them.) Huancané, a northern dialect sharing a number of features with La Paz, is also peripheral in sharing certain non- La Paz attributes with the southern and intermediate dialects. (Figure 10-2 distinguishes.central from periph- eral dialects.) In some cases features cut across regional lines. For example, Morocomarca, in spite of its remote- ness from La Paz, shares with it certain features lacking in other northern and southern dialects.
