[Live unconcernedly, live well!]
About four years ago I stumbled across this book in a used-book store. It was written/compiled in the 1860s by Manuel Garcia Rejon and published in Mexico.
The price was $1.
I bought it and for no good reason decided to study the language. This led to other vocabularies, tribal resources and materials from the good folks in the Comanche Nation itself and I am still none too fluent, but I work at it each day.
I am grateful to this book for starting me down this road and any Western fiction fan or Western history aficionado might find some enjoyment in browsing the pages and wrapping the tongue and mind around some of the unusual pronunciations and concepts.
