Words may be called interlaced if composed of overlapping shorter words. Fagot is a good example, with its regular overlap of fag, ago, and got. It also contains fa, go, a and o forwards, and to, tog, and toga in reverse order. Thus this five-letter word has ten component words, a ration of two to one for a measure of interlace.
