A number of these pairs arise from the contrast between the -able suffix and the -al suffix, such as admirable/admiral and removable/removal. There are several doubtful cases where the presence or absence of a syllabic consonant affects the syllable count and the decision about whether the pair is minimal. Thus sociable/social is not in the list but sociably/socially is. The pair subaltern/sultan shows up in the lists, but subaltern is clearly three syllables while sultan is two. Similarly fabled is clearly two syllables, while failed is usually analysed as a monosyllable. The same applies to stablemate/stalemate, though the difference is less striking. There is also a problem when the /b/ comes between a diphthong and a vowel leaving a triphthong when the /b/ is omitted, as in labour/layer.
The bass homograph yields the two pairs bass/ace and bass/ass. The pair BBC/EEC is not quite minimal but is close enough to be retained in the list. I have discarded all other cases where two /b/ consonants have been contrasted with nulls, as in bible/aisle.
