ROOK/rʊk/

A chess piece that moves horizontally or vertically.

The rook can travel straight along either the board's ranks or files.

A single recognizable castle-topped rook on an otherwise empty chessboard, with subtle straight directional arrows along its rank and file showing its horizontal and vertical movement.
Etymology

Persian rukh was a name for the chess piece, but its original meaning is unknown. It may be connected with an Indian piece-name derived from a word meaning “chariot.”
