When two consonants are pronounced consecutively within a word, the second consonant's symbol is written in a special sub-consonant form which is placed below the first consonant. The sub-consonant always follows the consonant in the pronunciation. The form of the sub-consonant is in most cases a smaller version of its consonant version but some look completely different from the superscript. The tables provided here are the lists of the sub-consonant and the consonant. (Huffman, 1970)
