Language Examples
Historical [ɔr/or/ar]→[r-colored vowel]— Widespread mergers in North American dialects where vowels are shifted and merged specifically when followed by the rhotic [r].
Historical [r]→[R/ʁ]— While usually r > ʁ, the correspondence between different rhotic realizations and their interaction with surrounding vowels like [y] is a key focus of dialectal research.
