What is "andhadhi"

Andhadhi is a unique kind of Tamil poetry constructed such that the last or ending word of each verse became the first word of the next verse. In some instances, the last word of the a series of verses becomes the beginning of the very first verse, thus making the poem a true garland of verses. Andha(m) means "end" and '‘Adhi'’ means "beginning". In Tamil Andhadhi was first sung by Karaikkal Ammeiyar
