What is the Onondaga's native language?

All the Iroquois tribes spoke their own languages; they are classed as belonging to the Iroquoian language family and all are closely related, but they are definitely different from each other and from other Iroquoian languages such as Erie and Huron.

For example the Oneida Word for fire is o·tsísteˀ. In Cayuga it is ode:kaˀ.

The Oneida Word for bear is ohkwa·lí; in Cayuga it is hnyagwai'.

The Oneida Word for water is ohne·kán or ohne·kánus; in Cayuga it is ohneganohs.

Only the last of these three Words clearly shows the connection between these two related languages.
