Hammett comes from an English surname which seems to be combined of Norman personal name Hamo/Hamon (the Norman form of Germanic haim meaning “home”) with the diminutive suffix coupled with the French diminutive -ette from French petite “small, little”, meaning “son of Hamo/Hamon”. The prefix ham- could also be from Anglo-Saxon ham referring to the flat wetlands, referring to someone who lived by or near a low-lying meadow.
