Interchangeable ch/sh and k/t characters

[Grove]

-----
But there’s another piece of “evidence” that, for example, t and k aren’t interchangeable:

k before aiin (20.6 percent) (n=810)
t before aiin   (9.0 percent) (n=356)
k before ain  (38.1 percent) (n=645)
t before ain  (12.4 percent) (n=210)

"t" seems to occur significantly less frequently with the “aiin” family than "k". "t" is more likely to appear with ‘o’ and "ch."

Except maybe if when the line starts with taiin and has tripled repeats using aiin:

<f40r.P.9;F>       taiin.ol.olaiin.or-{plant}dain.okaiin.okaiin.okaiin.daram-

<f86v3.P1.3;H>     taiin.ytaiin.ytaiin.ytaiin.or.ar.ytar.am-
