Lilatilakam (IAST: Līlā-tilakam, "diadem of poetry") is a 14th-century Sanskrit-language treatise on the grammar and poetics of the Manipravalam language style, a blend of Sanskrit and early Malayalam used in the Kerala region of India.
Lilatilakam is an anonymous work, generally dated to the late 14th century.
[1] It is attested by two (possibly three) manuscripts and is not referenced by any other surviving pre-modern source.
[2] In 1909, Appan Thampuran published a translation of the first part of Lilatilakam in the Malayalam magazine Mangalodhayam.
[3] Lilatilakam (literally "diadem of poetry"[4]) calls itself the only disciplinary treatise (shastra) on Manipravalam, which it describes as the "union" of Sanskrit and Kerala-bhasha (the regional language spoken in Kerala).
