griddle (n.)

"gridiron, grated utensil for broiling over a fire," 1680s, from French gril, from Old French greil, alteration of graille "grill, grating, railings, fencing" (13c.), from Latin craticula "gridiron, small griddle," diminutive of cratis "wickerwork," perhaps from a suffixed form of PIE *kert- "to turn, entwine." Grill-room "lunchroom where steaks, chops, etc. are grilled to order" (1869) came to be used for "informal restaurant," hence grill as a short form in this sense (by 1910). In many instances, Modern English grill is a shortened form of grille, such as "chrome front of an automobile."

1839, shortening of gridiron or griddle. City planning sense is from 1954 (hence gridlock). Meaning "network of transmission lines" first recorded 1926.

cooking utensil for broiling over a fire, early 14c., griderne, alteration (by association with iron) of gridire (late 13c.), a variant of gridil (see griddle). Confusion of "l" and "r" was common in Norman dialect. Also a medieval instrument of torture by fire. As the word for a U.S. football field, by 1896, for its lines.
