wheat (n.)

Old English hwæte "wheat," from Proto-Germanic *hwaitjaz (source also of Old Saxon hweti, Old Norse hveiti, Norwegian kveite, Old Frisian hwete, Middle Dutch, Dutch weit, Old High German weizzi, German Weizen, Gothic hvaiteis "wheat"), literally "that which is white" (in reference to the grain or the meal), from PIE *kwoid-yo-, suffixed variant form of root *kweid-, *kweit- "to shine" (see white; and compare Welsh gwenith "wheat," related to gwenn "white"). The Old World grain was introduced into New Spain in 1528. Wheaties, the cereal brand name, was patented 1925.
