<< Sloppy of me! /yaa it is, of course. I just mentioned it because
itis the only way I can see them getting the "ya" from "i". Come to
think of it, wouldn't paticca + i => paticcaya anyway? >>
"pa.ticca" is an absolutive and is used in the two etymologies to
explain the sense of the prefix "pati" in "paccaya". "pa.ticca" also
contains the root "i". How the forms "pa.ticca" and "paccaya" are
arrived at, I'm sure, are explained in the grammatical suttas. In the
second article on "eti" in CPD one will see our two etymologies from
the Saddaniiti quoted and included under sense 3: to evolve, arise
(right near the end). I think your "pa.ticcaya" is probably
non-existent in Pali. I found two more etymologies on the word
"paccaya" in the Padaruupasiddhi (Ruup 362) with further explanations
given in its .tiikaa. Here, "eti" is glossed with "aagacchati" and
"pa.ticca" with "nissaaya".
