Montes Giraldo (1978) identified, within certain phytonyms collected in Cundinamarca and Boyacá (Colombia), a ch ~ rr alternance and a frequency in suffixes -ca, -que, -cha, -che which he classified as linguistic features of the Muisca language. The former indicates a dialectal feature while the latter indicates classifying suffixes for plant names. In this paper, the loanwords of Muisca origin (Giraldo Gallego, 2012, 2015) which have been identified by using the two criteria mentioned above are presented. The data show that the proposal of Montes Giraldo is up to date and reveal other suffixes which could also work as classifiers.
