My percocious cousin developed a capacity for language early on. Earlier, that is, than he developed the needed vocabulary. So he was speaking in coherent complete sentences, which were about half english and half words he completely fabricated. Only some were ever decoded, and the only one I can remember right now (danged memory block!) is his word for fire-engine: Synanoonie. He also had some notable ones for various zoo animals which slip my mind at the moment
