On the Indian side, a very long bridge connects to a small island known as Pamban.
This bridge has a part that can be raised for tall marine vessels to pass through.
"Eliya" implies an "open place", a "cleared place", or a region held as a "common". hist: Ancient Buddhist shrine and Dagoba, referred to by de Queyroz Map map Achchuveli, Achuvely (Yapanaya) ATHURUVAELLA ⚓name The etymology of this place-name is similar to that given in preceding discussions. This name is often found in southern maritime areas in SL.
This is a location of ancient Buddhist ruins; de Queyroz, discussing the fall of Jaffna says "It remained under the Portugezen sway for upwards of 40 years, wrested from the Emperor by Philippo d'Olivero when he defeated the Cingalezen forces near Achiavelli (Achuvely) by the great pagoda". In Tamil, Ala, Alaru Alakkar, Ceru etc., are used for mud.
On the other hand, the sinhala word "Attana" refers to a plant species (Latin Dathura Alba, or Datura metal, Tamil "Umaththai").
Its occurrence in Sinhala place names is well established.
Jayakumar, and also Mahadevan have discussed 2nd BCE Sinhala influences extending into South India itself.
It should be noted that race or ethnicity , as understood today was of little consequence in ancient times, when it was the caste that was most important. Velu Pillai in Yalpana Vaibhava Kaumudi devotes a whole chapter to Sinhala place names in Jaffna.
The plant as a whole is a narcotic, and the Tamil name "Ummaththai" is probably derived from the Sanskrit/Pali word which means (causing) "madness", or "ummmada" in Sinhala. "Athuru" mean "nearby" in the present context (also, it may in other contexts mean "supplementary", or "inter-mediating").The study of toponyms also shows the cultural closeness of these two language groups, immensely influenced by Sanskrit (in this document we use the name 'Sanskrit' to include all proto-forms related to the language of the Rig Veda, and not just the systematized form). The claim of an exclusively Tamil, "Traditional Homeland", or a "Tamil Kingdom ", initiated officially by the 1949 Maradana resolution of the Ilankai Arasu Kadchi has been the most serious threat to this.The North and East of Sri Lanka were populated by people who were largely Sinhala-speaking Buddhists till about the 12th century. See Achchankulam (Mannarama [Mannar} district ) ATTANAVAEVA, ⚓name Meaning: There is no "achchan" listed in the usual Tamil dictionaries and Lexicons; however, close forms like 'accan' may be listed.Nevertheless, the Palk straits shielded the Island sufficiently to create unique biological species, a unique "Sinhala language" (see James W.Gair and others) as well as a Tamil culture distinct from that of Tamil-Nadu.
Note that the old names "Rama bridge" (irāma;-cētu; இராமசேது in Tamil consistent with the Tolkkappiam rules), or Ramasethu රාමසේතුව , was replaced by "Adam's bridge" in 1804 by the British surveyor James Rennel.
