A flat framework made of parallel metal bars, often used for cooking meat or fish, or a term used in football to refer to the field of play or the game itself.
The chef placed the steaks on the gridiron to cook them evenly.
Gridiron → The word originates from Middle English 'gridiroun', which is derived from 'grid' (meaning a grating or lattice) and 'iron' (meaning the metal). It refers to a framework of iron bars used for cooking or grilling, resembling a grid.
Picture a 'grating' ('grid') made of 'iron' — that's why a gridiron is a cooking framework.
