9, I E nawan; Dak na (pchi) wan-ka.
10, I E dwakan; Lat decem; Dak wikchem-na.
5, I E k = Dak z otherwise sustained but not proved. Kw = kp = tp = pt, t and k being interchangeable before labials in Dak.
7, Neither A S seowon nor Dak shakowin are legitimately deducible from saptan. Perhaps sakan, sakwan was the true base.
8, Either Gk h or Dak sh may equal I E s. Dak d for I E t is rare but S. hd, Y. kd is a favorite combination.
9, I cannot explain inserted pchi.
10, In Dak m and n are interchangeable before labials, but m for I E n is here unsupported.[I] D cannot stand before w in Dak.
FOOTNOTES:
[I] Whitney Skt Gr 487 appears to regard m, as in Latin decem, the original nasal.
