Notes: Reconstructed for the PEC level. An expressive root with several irregularities: the most severe one is PA *χ:- instead of expected *q:-. Other irregularities are mostly assimilations (in PN: *q̇- < *q- before *ṭ; in PD: *-t < *ṭ after *q-) or dissimilations (in PTs, where -ṭ- would be expected). All this is rather usual in a root with two stops (especially in an expressive one).
