Derivational etymology implying a series of formal modifications. The initial ὑ- orients toward a verb with the preverb ὑπο-, ὑφ- before a verb with initial aspiration, and then the φ is assumed to be changed into β. The final syllable -ρις echoes χάρις, therefore the derivation yielding χάρις is transposed to ὕβρις: χάρις : χαίρω :: ὕβρις : x = *ὑ–αιρω. therefore ὑφαιρέω (with contraction ὑφαιρῶ). The exact parallelism would yield a form *ὑφαρις, then *ὑβαρις and through syncope ὕβρις. The ghost form *ὑβαρις is the one underlying the *ὑπόβαρις, which looks like a reanalysis of ὑ- as the monosyllabic variant of ὑπο-, found in Aeolic (Hom. ὕββαλε). From the semantic point of view, the etymology is baseless.
