This article is mainly concerned with what I will call Forwards and Backwards words, in which the letter progress forwards through the alphabet to the middle of the word, then backwards. The reverse, Backwards and Forwards words, are also dealt with. However, to begin, I recapitulate the simpler cases of words in which each successive letter occupies a later position in the alphabet (which, clearly, I must call Forwards words), and those in which each successive letter occupies an earlier position in the alphabet (Backwards words).
