Initial change/collapse not recognized

[aaronfay]

In the case of this collapsed preverb ka- itwewina is doing the right thing:

k-âcimostawak (ka-âcimostawak)

However with initial change in the mix, this collapsed preverb combo does not get recognized:

k-êsi-pimâcihocik (kê-isi-pimâcihocik)

(reference kwayask ê-kî-pê-kiskinowâpahtihicik p18-13)

[aarppe]

We changed spelling relaxation in the analyzing FST so that a preverb-final vowel can be dropped in all circumstances (If that somehow results from initial change, that shouldn't matter, but I'm yet checking). So, with the latest FST, I do get the following analyses:

hfst-lookup -q src/analyser-gt-relaxed.hfst
k-isi-pimâcihocik
k-isi-pimâcihocik	PV/ki+PV/isi+pimâcihow+V+AI+Cnj+3Pl+Err/Fra0.000000
k-isi-pimâcihocik	PV/ka+PV/isi+pimâcihow+V+AI+Cnj+3Pl	0.000000
k-isi-pimâcihocik	PV/ke+PV/isi+pimâcihow+V+AI+Cnj+3Pl	0.000000

... and it appears to work in itwêwina, cf. https://itwewina.altlab.app/search?q=k-isi-pim%C3%A2cihocik

Is it likely then @aarppe that -êsi- would need to be recognized as a preverb in order for Itwewina to recognize k-êsi-pimâcihocik?

[aarppe]

Yes, êsi- would need to be specified as a preverb in the LEXC source, for verb forms with êsi- to be recognized.

Here's another example involving initial change that isn't recognized by itwewina:

nik-êtwân  "I will say"

(kwayask ê-kî-pê-kiskinowâpahtihicik p44-33)

Presumably a collapsation of nika-itwân, but possibly nikê-itwân?
