I am

Do you remember how ejstin can mean "he is," "she is," or "it is"? Do you remember our discussion about how a Greek verb can make reference to its subject? This is true for all Greek verbs.

εἰμί all by itself means "I am"; you don't have to add the specific word of "I." But sometimes the Greek speaker wanted to be specific or emphatic, and he included ἐγώ with εἰμί.

Important: the English verb "is" has many forms: am; are; is; was; were. The actual name for the verb is "to be." When I speak of this verb, I will call it the verb "is" or the verb "to be."
