Pronunciation note: greasy is almost always pronounced as/ˈgrizi/Show Spelled Pronunciation[gree-zee]Show IPA, with a medial/z/[z], in the South Midland and Southern U.S. and as/ˈgrisi/[gree-see], with a medial/s/[s], in New England, New York State, and the Great Lakes Basin. Speakers of New Jersey and eastern Pennsylvania are divided, with some using/s/[s]and some using/z/[z]. Standard British English reflects both/z/[z]and/s/[s]pronunciations and British folk speech is also divided regionally, with/z/[z]heard in the eastern counties and/s/[s]in the central and western ones. Both pronunciations were brought to the colonies, where the present U.S. pattern emerged.
