It depends how you define Hybrid in regard to natural language. But I think we can understand how English developed when we look at the history.
What is quite unusual is the decision made about 1500 or a bit later ? to include a lot of Latin or Latin derived words, and some Greek, but I guess we should be grateful, we have a large vocabulary now to choose from, but a confusing one in some instances, where we do not know the etymology personally, and cannot ourselves see how the word came to be used as it is ! But this was not language evolving by osmosis.
Hence my Dictionary of Etymology gets some use !
