Extending Darryl Francis's discourse upon monoconsonantal words in the February 1979 Word Ways, I list below a type collection of biconsonantal words. A biconsonantal word is defined as a word which contains two different consonants, each one appearing once or more, and with no restrictions on its vowels (selected from AEIOUY).
