thank you so much for this very informative reply. Now I understand.
Fleksy had the same approach, but I Imagine you cannot use their dictionary can you. Shame because the work has already been done in terms of probability. Although I find that Fleksy makes much more mistakes in French than it does in English.
Anyway, Tell me if I can help, and how ; I am just starting to realise the extents of the work.
