The table of sound representation heretofore given serves to compare the materials of the main body of the Dak with Fick's I E bases. The results are, however, in many cases ambiguous. Besides the number of accidental resemblances of the Dakotan to the I E languages seems, to be much greater than the whole number of similarities between Dakotan and Algonkin languages. Dak anapta is identical with I E anapta in sound, closely similar in meaning. Dak a-na-pta is prep. a = Icel a on, na prefix converting root to verb, and pta separate; cf I E pat fall, also open (Lat pateo). I E an-apta is an negative prefix, and apta participle of ap attain. My father compared Dak chepa fat with Lat adeps. I have since found Min idip fat almost identical with Lat stem adipi. I E and Lat d and p are nearly always d and p in Min; but it is extremely doubtful whether the words are related. On the other hand there is little apparent similarity between Eu karpya shoe, and Dak hanpa shoe; but the Dak word represents the Eu as accurately as possible; similar forms are found in every Dakotan language, and it seems scarcely possible to me that the similarity can be accidental.
In giving a few additional examples of similar roots I select those that are the most obvious, rather than the most certain. I exclude those not in accordance with sound representation, and the analogies of such allied Dakotan and I E forms as are known to me.
Where the Dakotan forms are not used as separate words it is indicated by a hyphen, before, if used alone as a verb stem, after if it requires suffixes. Where the root is found primarily combined with only one suffix or prefix the derivative form is given. In some cases the Dak root has one of the meanings given in one combination, another in another.
