Ancient Greek Athens' name was Athenai , in plural. However, in earlier Greek, such as Homeric Greek, the name was in the singular form, as Athene and was then rendered in the plural, like those of Thebai and Mukenai. The root of the word is probably not of Greek or Indo -European origin, and is a possible remnant of thepre Greek substrate of Attica.
Previously, there had been other etymologies by scholars of the 19th century.Lobeck proposed as the root of the name the word ( athos ) ( anthos ) meaning flower, to denote Athens as the flowering city. On the other hand,Doderlein, proposed the stem of the verb st. thao , st. the , "to suck" to denote Athens as having fertile soil.
It is very simple to say Athena in Tamil as Aathi Annai. Aathi means primordial and Annai means Mother in Tamil. Hence Athena means a Primordial Goddess Without any specific name attributed to her.
In ancient times, there were various explanations for the name Aegean . It was said to have been named after the Greek town of Aegae, or after Aegea a queen of the Amazons who died in the sea, or Aigaion, the "sea goat", another name of Briareus , one of the archaic Hecatonchires , or, especially among the Athenians, Aegeus,the father of Thesus , who drowned himself in the sea when he thought his son had died. A possible etymology is a derivation from the Greek word , aigialos = aiges (waves) + hals (sea) ),  hence meaning "sea-shore".
If Athena is Aathi Annai , the name Aegean sea is the corrupted form of the Tamil Word Aathi Ayyan . Ayyan means Great Father .
The Metéora, "suspended rocks", "suspended in the air" or "in the heavens above" - etymologically similar to " Meteorite". Hermits lived in hollows and fissures in the rock towers, some of which reach 1800 ft (550m) above the plain. This great height, combined with the sheerness of the cliff walls, kept away all but the most determined visitors.
The name Meteora is similar to the Tamil name Mettur or Mettu Worai yur. M[a]edu means High land in Tamil. Ur means town [[ex: Thiruchenthur, Thiruchur , coim batore] and Worai means to live . Worai -- -- videm means dwelling place . Hence Mettu worai of Tamil [ living or dwelling in high lands---of Meteroa] had corrupted to become Meteroa in Greece .There is a place in Tamilnadu ,south India, in Salem district called Mettur where there is a dam for storing the kauvery river water.
Kalabaka , Kalabáka , alternative transliteration Kalambaka ) is a municipality in the Trikala regional unit, part of Thessaly in Greece . The Meteroa monasteries are located in the town. The name "Kalabaka" was given 6-7 centuries ago. It is of Turkish origin and means "powerful fortress". It has been Anglicized variously as Kalampaka, Kalambaka, Kalabaki, and Kalabak.
The name kalabakka is phonetically similar to the names of the villages or townships in Tamil nadu --capital city Chennai [Madras]. They are Kelambakkam , Aachirupakkam , Kodampakkam,Pattinapakkam, Adampakkam and Urapakkam. .Here pakkam means pakk'am i.e ' by the side of it' . For example; Pattinapakkam means the place by the side of the seashore . Kalabaka would have been called as Kolambakkam in earlier times even before 6 th century.. Kolam means kole or planet in Tamil .[if we read as KALAM -- it is the pot hanging from the sky namely Vinkalam. Vin means sky and kalam means skypot or planet]. For example: poovi kolam means planet earth. The word poo kolam' and maa kolam' signify the drawings of position of planets on auspicious days drawn with flowers or flour by Tamil women in the front yard of their houses. Since kole is a hanging/suspended one in the sky the name Kalambaka should signify a place by the side of the hanging/suspended kole, namely ,the Meteroa . well! What does the name Trikala signify ? Does it mean three kolam [koles-planets] or the Tharai [floor] kolam [ in worship/respect of the hermits/ancestors living in the Meteroa ] similar to that of Dravidian Tamil women's drawings, Maa kolam.
In Greek Mythology , Delphi was the site of the Delphic oracle, the most important oracle in the classical Greek world, and a major site for the worship of the god Apollo after he slew the Python , a dragon who lived there and protected the Navel of the earth. The name Delphoi comes from the same root as delphys , "womb" and may indicate archaic veneration of Gaia, , Grandmother Earth , and the Earth Goddess at the site. Apollo is connected with the site by his epithet Delphinios , "the Delphinian". The epithet is connected with dolphins in the Homeric Hymn to Apollo (line 400), recounting the legend of how Apollo first came to Delphi in the shape of a dolphin, carrying Cretan priests on his back.
If Delphi is the navel of earth, the root word for Delphi cannot be Delphoi which means womb in Greek. Undoubtedly Delphi is the naval of earth since there lived the great Python which is nothing but the Umblical cord attached to the navel. [refer my article on medical emblem and snake symbolism ]. So the root word for Delphi must be related to the word navel or umbilicus.instead of womb. Remember there is an ompaholos on Delphi.
The Tamil word Thoppul means umbilicus. The word Thoppul comes from the word Thoppai. The word thoppai comes from the word Thole+ pai. Thole means skin and pai means bag . Hence Thoppai [bag made of skin ] means tummy [abdomen]. Thoppul [ul means ullae-- in/ inner or enter/entry ] means the entry point into the thoppai, ie. Umbilicus.. The word for Umblicus in Tamil i.e Thoppul would had been coined colloquially in those times as Thole pai [ bag of skin ] by proto Dravidians and later the word Thole pai itself would have corrupted in to tholepi and further later into delphi by those people who were alien to that civilization .Remember, the Dravidians are snake worshippers. It seems there were a group of people who ruled over the world in the ancient past from east to west with Greece - Delphi as their central lands. Or will it be like this? A group of people had migrated from Delphi-Greece towards east and west but then their original place , their land of origin was the Delphi , their umbilicus.[of their civilization] Perhaps Delphi, the umblicus , could be related to only snake worship of some people as snake represents the Umbilical cord/placenta and that the umbilicus is nothing to do with their migration.
