Description
The code consists of the first letter of the word, plus values for the next three additional consonants. If there are less than three consonants, 0s are placed in the code. The codes are values given to consonants. Words with a similar arrangement of consonants have similar codes, regardless of the actual spelling. Also, similar sounding consonants can have the same code.
