roiling

Usage Note: The verb roil means literally "to make muddy or cloudy by stirring up sediment," and this meaning has given rise to a number of figurative uses. Roil can also mean "to be or cause to be agitated." Not surprisingly, the synonymous verb rile actually began its existence as a variant of roil. The figurative uses appear to unsettle many Usage Panelists since several seemingly unremarkable examples could not elicit acceptance from more than a thin majority. In our 2002 survey, the Panel was given both transitive and intransitive examples. The transitive example The lyrics of the song roiled some Asian students, who felt they were racist was acceptable to 52 percent of Panelists. The phrasal verb roil up found even less favor. Only 44 percent accepted the sentence The administration's comments have roiled up the university's professors, who felt the administration was declaring war on tenure. For intransitive uses, the Panel was no more sanguine. Some 54 percent accepted The controversy continued to roil just two days before the primaries. The literal use meaning "to move turbulently" found even fewer takers, with 34 percent accepting It was like wading through surf when a mountainous breaker is roiling toward you. According to most dictionaries, all these uses should be acceptable. The survey results suggest then that many people see these uses of roil as malapropisms for rile. Writers who count themselves in this number can use a synonym like upset or disturb for the transitive uses or boil or roll for the intransitive ones.
