Cobnut is an alternative name for the hazelnut (hazel is by far the older term). Its original form, first recorded in the fifteenth century, was cobble-nut (cobble, as in cobble-stone, was originally a diminutive form of cob, ‘round lump’, now used for a sort of loaf), but cobnut is probably of equal antiquity, although documentation of it has not survived.
The term Kentish cob is actually something of a misnomer, for it is applied to a variety of filbert, a slightly different species from the native hazelnut. It was first raised by a Mr Lambert of Goudhurst in Kent in 1830.
