Proto-North Caucasian: *pĭrpi
Meaning: beech-tree, plane-tree
Notes: Reconstructed for the PEC level. The B series in PTs could suggest a laryngeal in PEC (*pHĭrpi), but there is no trace of it in any other language; it is possible that Khvarsh. pepe is a result of secondary assimilation ( < pipe), which would allow us to reconstruct *pipe A for PTs.
