Agreed, but since we know that not all possible words do exist, even in the list of words (as opposed to the list of tokens) the probabilities 'per slot' could be unequal, i.e. for example 0.5 that it's empty and the other 0.5 divided over various options. Thus, the Roman number system may not be the only choice after all. Of course, the fact that the list of words does not display a complete binomial tree is a problem for this whole theory. At the same time, the observed factor 12 in the word count for each given word length could suggest various ways out of this. Like I said, more thought needed. The idea that the binomial word length distribution could be due to the combination of a smaller number of (largely) independent sub-groups with individual symmetric length distributions does of course take us back to the prefix - stem - suffix construction. Here, again, the Roman number system (but also Greek and Arabic) have the interesting property that numbers over 1000 are built using the character set for the smallest numbers (using a special indicator for the multiplication by 1000). Lastly, the various not-quite-but-almost binomial distributions shown in Jorge's posts mostly differ in the areas of extreme word lengths. When plotted on a linear scale as in the figure on Jorge's web page, the difference might not at all be noticeable.... Cheers, Rene
