what does Eid mean?

Salaams (peace).

Well as in all matters related to Islam, Eid and Eid greetings too feature the unique characteristic of Islam: pure, distilled & uncompromising monotheism. "Worship the Creator and do not worship His Creation or His Creatures".

The Eid greeting for Eid-ul-Fitr is:
"Allaahu akbar. Taqabbalallaahu minna wa minkum".
Translated: "Allah is Supreme. May Allah accept (our prayers, fasts & charity) from us and from you".

Allah is the name of the sole, unique, uncreated Creator. 'Allah' in Arabic means "The God"; al-ilaah.

He is the only entity & deity worthy of submission, loyalty, obedience, devotion and worship.

He has no parents, nor does He have any progeny. He begets not, nor is He begotten.
He is free from all needs and desires.
He does not need food, sleep, rest, recreation, entertainment, mates, sex...
He does not need anyone's help.
He is Most Benevolent, Most Merciful, Loving and Just.

He is the Creator of all that exist besides Him. And besides Him, there is no other god or goddess. Period.

Neither does the Roman empire/civilization nor the Greek empire/civilization nor their pantheon of several gods and goddesses exist today. Visible lessons.
