These pairs exhibit either the loss of a complete opening or closing prominent syllable, eg arbiter/bitter and bizarre/biz, or the loss of an internal vowel where the surrounding consonants are capable of clustering, so that the second word seems to bear little relation to the first word, eg regard/rigged or starring/string. In both cases an unstressed component moves up to acquire stress, so that the contrast is not strictly minimal, though there are a few cases where the deleted /ɑ/ vowel is unstressed and the contrast is more truly a minimal pair, eg arcane/cane, radar/raid and sonar/sewn.
The density is 1.47%. There are 47 semantic contrasts in the list, giving a semantic loading of 77%.
