Panicker
Panicker (sometimes Panikkar) is an Indian title or last name used by members of various communities in the state of Kerala. The Kaniyar community of Kerala, particularly central and northern region, by virtue of their past traditional occupation as teachers of a martial art ( Kalari) are commonly known as Panicker. Some members of the Nair and Ezhava castes in the Hindu religion and also some Christians from the Syrian Catholic, Syrian Orthodox and Mar Thoma churches also hold this last name.
