surrounding tribal tongues ; one principie that I would specially men- 
tion is in the formation of nouns by tlie addition of prefixes, thus from 
the Choroti u the Vejez malee ky-u (a liorn) ; from the Suhin eyi the 
Lengua-Mascoy with the prefix p malee paiya (a mosquito). -The 
chapters on derivation not only give the partióles, prefixes and suffixes, 
but also sorne of the important root words which can be traced through 
many of the Chaco languages and frequently in Quechua and Mojo as 
well. The sexual valué of the letters will also repay study and com- 
parison as well as the tribal, sexual or euphonic interchange of letters. 
The iníluence of the Choroti, or perhaps better expressed the 
Mataco-Choroti, has been very widespread. Nations that have come 
into the country and have mingled with these apparently original 
peoples have used their language as a base and upon it have built 
their own partióles. Birds, animáis and trees new to the experience 
of the immigrants, and for which tliey evidently liad no ñame on their 
arrival, still retain for the most part the original ñames of the Mataco- 
Choroti. This iníluence can be specially seen in the oíd Lengua 
(Aguirre), the Lengua-Enimaga or Towothli, and the Suhin-Chunupi ; 
to some extent in Paiyaguá and in that medley of tongues known as 
the Chiquito. 
I am indebted to my colleague, Mr. W. Barbrooke Grubb, for the 
Towothli words which he collected at various times, which with a few 
others I compiled into the accompanying list, 1 copying out at the same 
time the Lengua and Enimagá words of Aguirre’s list for comparison. 
A cióse study of these words reveáis many intímate touches with the 
present Choroti, together with a Mojo iníluence which is also to be 
found in the Choroti itself. 
To Mr. Andrew Pride, my friend and colleague, I owe my first 
insight into the Suhin language, and his vocabulary which is liere given 2 
formed my groundwork for the study of the Chunupi or western Suhin. 
In this language the two influences of the Mataco-Choroti are very 
apparent. In the same breath they use a distinctive Mataco word 
with another peculiar to the Chorotis, e.g. the Vejoz Eyáj (the jaguar) 
and Choroti Nuu (the dog), and Tenuk (the domestic cat). Contrast 
this with the Toba words Kid-yuk (the jaguar) and Pi-yák (the dog), 
distinga ished from cach other by a prefix only ; or a similar formation 
with the n root in the Towothli Te-nuk (cat) ; Káma-te-nuk (the jaguar) ; 
No-nak (dog). 
I regret not having secured more words of the second dialect of 
the Choroti, 3 which in some respeets is more primitive than the dialect 
specially studied, but which in any case is a simple dialectal difference 
and does not ofier the varied changes of the Suhin or Towothli.
