ferret: [14] A ferret is, from an etymological point of view, a ‘thieving animal’. The word comes via Old French fuiret or furet from Vulgar Latin *fūrittus, literally ‘little thief’. This was a derivative of Latin fūr ‘thief’, which is related to English furtive. The verbal senses ‘search about’ and ‘search out’ developed in the 16th century.
