Proto-Indo-European edit

Reconstruction edit

A hotly disputed root. Derksen prefers to reconstruct *perH-, to which he also assigns Slavic *pero.[1] Matasovic reconstructs *perHt-.[2] Kroonen reconstructs *pterH- under the assumption of a connection with Ancient Greek πτέρις (ptéris),[3] a connection Derksen and Matasovic do not find phonologically likely;[1][2] Beekes considers the term a later Greek formation.[4] The only point of agreement between them is that the majority of descendants generally assigned to this root, with the exception of πτέρις (ptéris), are definitively cognate.
