 It was Veeramamunivar who introduced the system of dotting the Tamil consonants (க், ங், ச், ... ) and writing the long vowels as ஆ instead of அர, கா instead of கர, etc.His biggest poetical work is the "Thembavani" (தேம்பாவணி - The Unfading Garland - an ornament of poems as sweet as honey), 3615 stanzas long on salvation history and the life of Saint Joseph.He also wrote a "prabandham" (a "minor" literature) called "Kaavalur Kalambagam" (காவலூர் கலம்பகம்), a grammatical treatise called "Thonnool" (தொன்னூல்), a guide book for catechists with the title "Vedhiyar Ozukkam" (வேதியர் ஒழுக்கம்), and "Paramarthaguruvin Kadhai" (பரமார்த்த குருவின் கதை - "The Adventures of Guru Paramartha"), a satirical piece on a naive religious teacher and his equally obtuse disciples.
