-σθ- in 1st pl pres ind mp ending

[Tugodum]

E.g., ἑζόμεσθ᾽ in Sophocles, OT 32. Perseus says "epic poetic," and I believe it, yet am wondering whether there is any regularity about it, as I failed to find anything to this effect in Smyth.

[seneca2008]

Neither Finglass nor Dawe mention the form in their commentaries.

[Tugodum]

I do not see it under ἕζομαι in LSJ, nor even in Cunliffe. So, I infer that it must be regular. But do any grammar books mention this form of 1st pl pres ind mp?

[seneca2008]

Goodwin 777.1 says the poets have μεσθα for μεθα

[Tugodum]

Thanks a lot!

Smyth, 465d

[Tugodum]

Oh, thanks! I should have searched better.

Note that it’s used only under metrical necessity. It’s morphologically odd (though frequent) and I don’t know how it came into being, but I suspect contamination from -εσθ- in the infinitive.
