5. I E -wa formed passive participles, adjectives and nouns. It is in
Dak a living passive participial suffix combined with the like suffix
-an, forming wa(h)an. When added directly to the root it raises the stem
vowel as in; Eu ku contain to be hollow; Lat cava; Dak -ko be hollow,
noun ko a hole; kawa open. After consonants the w becomes p; I E akwa
water of ak; Gothic ahva river; Dak wakpa river.

6. I E -ma, -mana, -man formed adjectives, present participles and
nouns; I E akman stone of ak, A S iman; Dak imni stone.

7. I E -ra, -la formed adjectives and nouns; Eu kira yellow; Old Slav
seru; Crow shira, Min tsidi, tsiri, Man psida, Iowa thi, Om thi, zi; Win
and Dak zi yellow; I E ghu pour; Min ghu pour; Dak zhu pour, ozhu pour
in, in ozhudan, Tit ozhu la full; Eu wasra spring of was; Icel vara, Lat
ver; Win wera spring; Eu tag cover whence; Welsh and Irish ti house, our
thatch; Win chira house; Man, Min, Om, Dak ti house; Aryan nira water of
ni; Tit Dak nila water; Om and Win ni water.

Ra, la is also a diminutive suffix in I E languages. It is the regular
diminutive suffix in Win, -ra, in Tit Dak, -la, in Yank -na, in Santee
Dak -dan also -na.

8. I E -an formed past passive participles whence our en in fallen, etc.
It is still the regular passive participial suffix in Dak either alone
or combined with wa. As Dak verb stems end in a vowel it is preceded by
a euphonic h. When added directly to the root it raises the stem vowel,
as in Eu wik whence Gothic veiha holy; Dak wakan sacred.

9. I have not found infinitive suffix -na in Dak.

10. I E -na was a passive participial suffix, developing also
denominatives. The Dak has perhaps a few relics; I E ku bring low, kauna
low; Dak ku- in kuchedan, also kun low. I E mi, diminish (mince); Yank
and Tit Dak mina knife.

11. I E -ni formed abstracts and nouns of agency. Possibly it is found
in; I E migh pour out water; Dak mini water; and a few others.

12. Two words containing -nu, are recognized by Schleicher as I E; I E
and Dak su bear; I E sunu son; Dak sun younger brother. I E and Dak tan
extend; I E tanu adj thin, noun body; Dak tan body.

13. I E -ta (our -d) formed the past passive participle, and nouns of
similar signification, in which uses it is tolerably frequent in Dak; I
E ski collect, arrange; Dak shki plait gather, skita bound together,
tied on; I E pu destroy rot; Min pu rot; Dak po in pon (=po an) rotten,
po -ta used up, worn out; I E sta stand, sta
