Phil and Eric tackle the mouth lexical set, and compare it, briefly to the price set. We reference Robbie Burns’ To a Mouse, and talk about how it evolved through the Great Vowel Shift from an /u/ vowel, to its present location, in the range of /æʊ/—/aʊ/—/ɑʊ/. Eric touches on Canadian Raising, and the two glossonomians explore the range of articulations, modulating the initial component of the “vector”, and then the final component.
