The eleventh Tirumurai was composed by Karaikkal Ammaiyar, Cheraman Perumal, Pattinattu p-pillaiyar, Nakkiratevar, Kapilateva, Tiruvalavaiyudaiyar, Nampiyantarnampi, Iyyadigal katavarkon, Kalladateva, Paranateva, Ellamperuman Adigal and Athirava Adigal. Nambi's "Tirutottanar Tiruvanthathi" followed an exclusive style of mincing Tamil and Sanskrit verses in "anthati" meter similar to "Tevaram" of the trio. Karaikkal Ammaiyar (550-600 CE) is the earliest of the woman Saivite poets who introduced the "kattalai-k-kali-t-turai" meter, which is a complicated structural departure from the old classical Tamil meters. The other meter used by Ammaiyar was an old "venba" and also an "antathi" arrangement in which the offset of one line or stanza is identical with the onset of the next line or stanza.
