This name, with variant forms Wyatt, Wiatt, Whyatt, Whyard, Guyat(t), Gyatt, Guyot and Giot, derives from Guy-ot, a French diminutive form of the German male given name Wido itself coming from the old High German "witu" meaning "wood" or the old High German "wit", wide. The name was popular among the Normans in the form Wi and in the rest of France as Guy; hence, the diminutive Wi-ot, Wi-ard and Guy-ot. One, Wiot de Acham was recorded in the 1192 "Pipe Rolls of Lincolnshire" and a Gwiot (without surname) in the 1203 "Curia Regis Rolls of Gloucestershire.

The first recorded spelling of the family name is shown to be that of Henry Wiot, which was dated 1273, "The Hundred Rolls of Cambridgeshire", during the reign of King Edward 1, "The Hammer of the Scots", 1272 - 1307.
