Languages are ingrown, he says. Left to themselves, "they grow hungrily, ceaselessly, and rampantly into available space," like kudzu. They are disheveled. Over time they grow messy, develop peculiarities, become "jerry-rigged [probably he intended jury-rigged. Sorry] splotches doing the best they can despite countless millennia of unguided, slow-but-sure kaleidoscopic distortion." They are intricate, developing ever greater complexities unless something interrupts the tendency. They are mixed. All languages bear the traces of encounters with other languages, and no language is "pure."
