"Eskrima" or "Escrima" refers to a class of Filipino Martial Arts that emphasize stick an sword fighting. Other terms which have entered into common usage include "Kali" and "Arnis de Máno" ("harness of the hand"); occasionally the abbreviation "FMA" ("Filipino Martial Arts") is used. Eskrima and Arnis are among the many names primarily used in the Philippines today to refer to these arts. The name Kali, although primarily used in the United States and Europe, is seldom used in the Philippines and in most cases is an unknown word. But due to the popularity of the term outside of the Philippines and the influence of foreign practitioners, the term Kali is increasingly being recognized and accepted in the Philippines. Kalis, as used in the Philippines, refers to a sword. It is commonly mistaken as synonymous to or a derivative form of kali (note: postfixing of "s" is not used in Filipino languages or dialects to indicate plurality). However, for all intents and purposes, Eskrima, Arnis, Arnis de Mano, Kali and FMA all refer to the same family of Filipino weapons-based martial arts.
