I don't understand the form ἠγέροντο. I am quite certain it is from ἀγείρω and that it is 3rd person plural middle or passive but I don't know if it is aorist or imperfect. The aorist form is given as having and Epsilon and an Iota, and the imperfect is (usually ?) build on the present tense stem, so that means again with an Epsilon and a Iota. Is this a unusual form or am I going stir-crazy?
Thanks.

Pharr has played a naughty trick, or at least has omitted important information here.

For mysterious reasons the middle aorist reduces the stem ‐ει‐ to ‐ε‐. Only consulting a Homeric dictionary makes this clear. Homer subjects poor ἀγείρω to many stem changes, including an aorist participle in ἀγρόμενος.

But you are correct to note that the imperfect is built on the present stem.

Hi,

This is a bit off topic. But as I've been dallying in morphology, here's a brief morphological aside on the word ἀγείρω: it seems to derive from the non-attested root ἀγέρ‐ιω (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 ἀγείρω. The same root, losing its epsilon, yields the 'zero grade' ablaut form ἀγρόμενος.

Cordially,

Paul
