> They also (as Douglas pointed out) obviate any need to lookAttempts to find a "real but highly non-obvious sound law" often lead to linguists attempting to fit a law that must be tailored to fit every case, with a strange set of env. and env. exceptions, that obviously doesn't come from reality but instead from attempting to fit regularity where none exists, making them unlikely.
