There are two main dialects: Gejaehl and Bor. The dialect presented here is Gejaehl. The differences between the dialects are as follows:
Gejaehl merges a and ɔ; Bor keeps them separate, and instead has æ e > e i.
Gejaehl has r > y syllable-initially and r > 0 syllable-finally.
Gejaehl has uy > wi.
Gejaehl has 3P -la after all vowels, whereas Bor has -i-a -u-a > -ya -wa.
Verbal pluractionality has been regularized in Bor, but the second-person markers are more common.
Inalienable possession is less irregular in Bor.
Bor has ly > y.
Bor is more likely to preserve -y- and -w- infixes from lost pretonic vowels.
Bor reflects *uˠ as -au, not -u.
Bor preserves Pl Kl clusters, for plosive values of P K.
Presumably there are also morphosyntactic differences, especially in the TAM system.
