Mohawk

One speaker of it said that Mohawk isn't just a form of speech. It is a holistic relationship to the cosmos.

Speaking Mohawk can require the memory of a bard and the lungs of a singer. It has compound words longer than German. To make it even harder, they are not necessarily pronounced the way they are written. For instance, tabotenonhwarori'taksen'skwe'tsherakabrbateniaa'tonhaitie is a word meaning "the fool comes tumbling down the hill." 

Noun roots are modified by adjectival prefixes sometimes as short as the letter "h." Burying someone is expressed by saying that you wrapped his body with the blanket of our Mother Earth. If you father a child you "lend him your life." The word "I" never stands alone. It always is part of a relationship. You don't say that you are sick. You say that the sickness has come upon you.

Mohawk also has a mood something like the subjunctive of Kurdish, Albanian, Navajo, Sanskrit and ancient Greek.

Alexander Graham Bell loved the sound of Mohawk and was made an honorary chief after creating an orthography of it. 

There are about 25,000 people in North American who identify themselves as Mohawk. Only about 15% of them speak Mohawk fluently, but some children are now texting in it and immersion classes are available for studying it.

The Mohawk are recognized as one of the tribes present before first contact with Europeans. They were feared for their ferocity, but held in check by a matriarchal government that required consensus. Much of upstate New York and the land to the north and east into Canada used to be their territory. But they sided with the British during the revolutionary war and lost.
