Analysis. catu- (four) + -rassa (corner). A bahuvrihi compound: "having four corners"; used as an adjective substantivized into a noun.
Etymology. catu- derives from PIE *kʷetwer- "four" (Sanskrit catvār-, Latin quattuor, Greek tettares, English four). The element -rassa is cognate with Sanskrit rasana "edge, corner" and possibly Greek errassa (in the sense of edge or border), from a root meaning "scrape" or "edge"; the image is of the corner as a sharp edge where sides meet.
