While it is good to have reference books, I don't really need to be going through dusty bits of my memory for -μι verbs while half asleep, even if someone did ask what the verb form of "hierophant" would be.
But if I'm going to do so, ειμι (I am) is an odd one to be working on. As far as I know, "be" is irregular in every natural language (and in English is not only irregular but "defective", having picked up forms from three distinct roots, as did both the Greek and Latin verbs for "carry," "fero" (it's basically the same in Greek, so I'll save myself typing the HTML entities)). [Does anyone know HTML coding that would indicate a smooth breathing over that ει?]Though, despite being the same present-tense form, they each acquired different past and future forms.
