Henry Nicol and Paul Meyer, 1911 Encyclopædia Britannica (1911)
“ Phonology.—The history of the sounds of a language is, to a considerable extent, that of its inflections, which, no less than the body of a word, are composed of sounds. This fact, and the fact that unconscious changes are much more reducible to law than conscious ones, render the phonology of a language by far the surest and widest foundation for its dialectology, the importance of the sound-changes in this respect depending, not on their prominence, but on the earliness of their date. ”
