This is a bit off topic. But as I've been dallying in morphology, here's a brief morphological aside on the word [face=SPIonic]a)gei/rw[/face]: it seems to derive from the non-attested root [face=SPIonic]a)ge/r-iw[/face] (here read the iota as consonantal). In Attic-Ionic the combination rho + consonantal i causes loss of the i with lengthening of the preceding vowel. This gives rise to the 'e-grade' ablaut form [face=SPIonic]a)gei/rw[/face]. The same root, losing its epsilon, yields the 'zero grade' ablaut form [face=SPIonic]a)gro/menoj[/face].
