In later centuries, these forms began to break down, but that is not my concern here. Here I have summarized the regular forms and included some comments on their use in electronic communication. To show deference, the sender's name might be placed last. For example, Areia Apollonioi khairein. Cynndarai khairein Apollonios.
N sends D many greetings.
Areia S.P.D. Apollonio. Omnibus salutem dicit Apollonius. The salutation was often followed by a wish of good health, which might be combined syntactically with the salutation. Greek A short wish might be appended to the salutation, and so would also be an infinitive. I pray you are well.
