AnnaStrophic,

Faldage is right: "J.", based on Shaw's ghoti idea. Dge from "edge" and -eigh from "sleigh". I forget the linguistic term for it, but instead of spelling it Dgeeigh, I dropped one of the Es and shortened it to Dgeigh.

It has been bothering me though. What is the linguistic term for dropping a duplicated letter in such a context?
