Proto-North Caucasian: *c̣_ădV
Meaning: rain, drizzling rain
Notes: Reconstructed for the PEC level. The PN form *derc̣ is a metathesis < *c̣erd (cf. also some modern forms reflecting *c̣erc̣ with assimilation), probably going back to the oblique base *c̣_ădV-rV- (other languages reflect also *c̣_ădV-rV-, cf. e.g. Akhv. c̣:ari, as well as *c̣_ădV-lV-, cf. PL *c̣at:al). The metathesis could also be favoured by analogy with *darc 'snowstorm' (see *ʒwVnćV).
