The name "chess" is derived from the Arabic word shatranj, which itself evolved from the Persian shatranj (from Middle Persian chatrang), ultimately tracing back to the Sanskrit word caturanga, meaning "four divisions of the military" (elephants, horses, chariots, and infantry). The Arabic term shatranj was introduced to Europe through the Islamic world, particularly via Al-Andalus (modern Spain), and influenced the development of the game and its terminology in Europe. The word "checkmate" comes from the Arabic shāh māt, meaning "the king is helpless," further highlighting the Arabic linguistic influence on chess.

mat means dead in Arabic not helpless btw.
Sjeik mat, meaning the sjeik is dead.
