pronunciation note For greasy

greasy is almost always pronounced as [gree-zee], /ˈgri zi/, with a medial [z], /z/, in the South Midland and Southern U.S. and as [gree-see], /ˈgri si/, 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.
