The main notions introduced into linguistic theory, especially into the theory of generative phonology, are included the notions of "simplicity" and "naturalness". Simplicity is a measure proposed by generative linguistic theory which would automatically assign factors to competing linguistic analyses that would determine which of them was most satisfactory. Naturalness too, is a notion introduced into this theory of generative phonology as an important criterion in evaluating analyses alongside such other criteria as simplicity.
There are three areas from which a natural explanation can be derived: logical, psychological and phonetic. This paper concentrates on the phonetic plausibility of an analysis.
