Re: Wildly different past forms for τρώγω, λέω, βλέπω. Why?

  These are the three verbs in modern Greek which are irregular in the sense that their non-continuous (perfective) form is not derived in any way from their continuous (imperfective) form.

And yes, each of these modern verbs [τρώ(γ)ω, λέ(γ)ω, βλέπω] are mergers of two different ancient verbs, where one verb supplied the present tense, and the other verb supplied the past (aorist) tense.
