hob

The word 'hob' has a fascinating journey from a personal nickname to a common household term. It originated as a familiar form of the name 'Robert' or 'Robin' (akin to 'Bob'), which in Middle English was used generically to refer to a rustic fellow, a clown, or a mischievous sprite. By the 16th century, this association with a rustic or goblin led to the term being applied to a clownish figure in morris dancing and, more importantly for the modern meaning, to a malevolent fairy or goblin believed to haunt homes. The crucial shift occurred in the context of the hearth, the heart of the home: the 'hob' became the name for the friendly spirit of the hearth, and subsequently, by metonymy, to the physical shelf or projection beside the fireplace where things were kept warm. This sense was later transferred to the heating surface on a modern cooker. The tool sense derives from a different, obscure origin, possibly related to 'hub'.

This word is a simplex form. It is a variant or shortening of the personal name "Hob" or "Robin," which were used in Middle English as generic names for a rustic, a clown, or a goblin. This connection influenced its application to objects associated with the hearth and home.
