Pencak silat (Indonesian pronunciation: [ˈpɛntʃaʔ ˈsilat]; also spelled penchak silat and pentjak silat) is an umbrella term for the indigenous martial arts created in Indonesia. The leading organization of pencak silat in Indonesia is IPSI (Ikatan Pencak Silat Indonesia meaning Organization for Indonesian Pencak Silat). The liaison body for international pencak silat is the International Pencak Silat Association or PERSILAT (Persekutuan Pencak Silat Antara Bangsa).
Pencak silat was chosen in 1948 as a unifying term for the Indonesian fighting styles. It was a compound of the two most commonly used words for martial arts in Indonesia. Pencak was the term used in central and east Java, while silat was used in Sumatra. In modern usage, pencak and silat are seen as being two aspects of the same practice. Pencak is the performance aspects of the martial art, while silat is the essence of the fighting and self-defense. It is often said by practitioners that there can be no silat without pencak, on the other hand pencak without silat skills is purposeless.
