Proto-North Caucasian: *räʔwV̄ ( / *ʔwärV̄)
Meaning: season
Notes: Reconstructed for the PEC level. The root must have originally denoted some span of time in spring or summer (cf. the specific meaning preserved in Lezg.). It can probably be discovered also in Hurr. compounds like šin-arBu/o 'two years old' (HU *-arwV, see Diakonoff-Starostin 1986, 64).
