I'd be delighted to forget about that! I sure am glad there aren't other special rules, such as "i before e, except after c."

Hmmm... it appears to generate correct results... here is the relevant passage from the research paper: [C]VCVC ... [V] where the square brackets denote arbitrary presence of their contents. Using (VC){m} to denote VC repeated m times, this may again be written as [C](VC){m}[V]. m will be called the measure of any word or word part when represented in this form. The case m=0 covers the null word. Here are some examples: m=0 TR, EE, TREE, Y, BY. m=1 TROUBLE, OATS, TREES, IVY. m=2 TROUBLES, PRIVATE, OATEN, ORRERY. The rule you've written returns the correct m for these words, as well as anything I've thrown at it so far. Thanks
