Twin's secret language

'Snap aduk, Cabenga, chase die-dipana' - at this mysterious command from one of the Kennedy twins, they both began to play with the doll's house. Grace and Virginia were believed to be

mentally retarded until it was discovered that they had developed a language of their own, complete with extensive vocabulary and syntax. 'Poto' and 'Cabenga', as they called themselves, were investigated by speech therapist Anne Koenecke at the Children's Hospital in

San Diego, California; she finally coaxed them into speaking a little English.

Their curious, private language was an example of ideoglossia, which is developed most often by identical twins apparently to exclude the outside world.
