This group is opened up to discuss the field of Historical Linguistics as a field belonging to Hermeneutic Science which was exemplified by Tolkaappiyar(c. 3OO BC). The postings may be technical and with active participation by all linguists especially the Dravidian and Indian linguists. Opportunity will also be taken to post classical articles and monographs related to these fields and which may later be uploaded in the Tolkaappiyam Campus. Linguists and amateurs interested in being aware of such dicussions are most welcome to join the group.
