Salasaca Quichua (ISO 639-3=qxl) is a Quechuan language, specifically of the branch referred to as Quechua A (Parker 1963), as Quechua IIB (Torero 1974), or the northern group (Landerman 1991); but see Landerman (1991) and Adelaar (2004) regarding doubts with respect to the classification of the different varieties. The variety described in this paper is spoken by approximately 12,000 people in Ecuador. The Salasaca ‘parroquia’ (Spanish usage in Ecuador of this word is for a non-religious administrative district), in Pelileo canton, in Tungurahua province, is divided into eighteen communities and Quichua is spoken in all of them. This variety is similar to that of others of the region and is included in the Stark & Muysken (1977) dictionary. Varieties of Quechua in this area do not have the more open allophones attested farther south (such as in Peru), and for that reason the Ecuadorian varieties are traditionally called ‘Quichua’ rather than ‘Quechua’.

Tilquiapan Zapotec is an Otomanguean language spoken in the town of San Miguel Tilquiapan, in the Oaxaca Valley, in the central part of that state, in southern Mexico (see Merrill 2005). There are about 2700 speakers according to the government census (INEGI 2000), though town authorities (p.c. 2004) suggest that about 7000 is a more accurate assessment of the population. The Zapotec language spoken in Tilquiapan is distinct from that of any other town, although nearby Santa Inez Yatzeche has 80–90% intelligibility with Tilquiapan, according to recorded text testing (Weathers 1973, Persons et al. 1985). With respect to sociolinguistics and language attitudes, speakers in Santa Inez and Tilquiapan recognize the close relationship, though people from each town tend to say that those from the other ‘talk funny’.
