Complexity
Chess spread rapidly (in historical terms) from the Subcontinent to the curiously diverse cultures further west, each leaving ineradicable traces of their time and culture. Persia bestowed the name to the game. Words, unlike mathematical formulae, both lose and gain in their sojourn through time and place. Aside from the usual etymological eddies, the development of the name flowed as follows. The Persian shah “king” came through the Arabic and the tangles of time to Europe as, among other variations, the Old French (e)sches, plural of (e)schek “check” derived from “shah.” From there it was but a minor simplification to the Saxon and Modern English word “chess.”
