It's important to note that "Iroquoian" is a language family, not a single language. While Seneca is one of the Iroquoian languages, there are several others, such as Cayuga, Oneida, Onondaga, and Mohawk.
Within the Iroquoian family, the Seneca language is sometimes called Onondaga-Seneca, reflecting its close relationship to the Onondaga language.
Today, the Seneca language is considered endangered. While there are still fluent speakers, the number is dwindling, and the language is not widely spoken among younger generations. Efforts are underway to revitalize and preserve the language for future generations.
