Kit–bit split
The kit-bit split is a split of EME /ɪ/ found in South African English, where kit [kɪt] and bit [bət] do not rhyme. It is not clear whether this is a true phonemic split, since the distribution of the two sounds is predictable: [ɪ] is used adjacent to velars (kiss, gift, lick, big, sing, kit), after /h/ (hit), word-initially (inn), generally before /ʃ/ (fish), and by some speakers before /tʃ, dʒ/; [ə] is used elsewhere (limb, dinner, limited, bit). Nevertheless because of the phonetic similarity of the two vowels in a word like dinner [ˈdənə], Wells argues that they belong to the same phoneme /ə/, while the vowel of kiss, big, hit, inn etc. belongs to the phoneme /ɪ/.
Centralized realizations of the vowel in bit is also found in New Zealand English. Unlike in South African English, this does not involve a phonemic or allophonic split.
