Any guess on what that 'third language' is? Sanskrit? Swahilli? Attic Greek? Mohawk? Incan? Tagalog? All of those?
I'm not entirely convinced nads has a first language (

). Given her Mexican heritage, maybe she speaks Nahuatl; Quechua, the language of the Incas, is spoken much farther south.
I've been told that my paternal grandfather (who died several years before I was born) was fluent in Russian, German, and Swiss German as well as English. He was a Volga German who emigrated to the US and lived here for more than 4 decades. So the odd language/dialect in that group is the Swiss German, which his family (my Dad, Uncles, and Aunts) found incomprehensible when they heard it.
