Word Ways


A. Ross Eckler


A word network consists of a collection of words of the same length, in which any two words that differ by only a single letter in one position (such as EAT and FAT, or STORE and SWORE) are joined by a link. A word ladder, originally invented by Lewis Carroll, joins two words in a network to each other by means of a path traced through successive links (such as EAT-BAT-BAND-BIN-PIN). Ordinarily, there are many such possible paths involving many different intermediate words.
