The Freedom of Delgarno

Delgarno created his language around 1655, during Cromwell's Protectorate. He had no precursors, he had no precedence to look at and say this is how people have done it before me. Delgarno was just doing this out of the top of his head, whatever came into his mind. There is such an amazing amount of freedom in that that modern day conlangers can't really expect.
