How on earth do we know this?  I asked this question to this group a few years ago and got no satisfactory answer.  I have a very simple need, which is a Latin spell-checker.  This would revolutionise our approach to digitisation of Latin texts. It is a relatively simple task, because I looked at the problem a few years ago.  I did not have the time or resource to solve it myself.  Perhaps I will look at the problem again.  But, then, there seems to be a whole humanities research industry devoted to 'digital humanities', so why hasn't someone provided a solution to this simple problem?

My pleasure: :)

(disclaimer: this Latin language spellchecker is a very basic tool, intended to help proofreading gross errors in OCRized Latin texts, or typos in the ones we type up ourselves; it in in no way exhaustive or perfect, and it DOES NOT PRETEND TO DO a latinist's job regarding the grammar; all it does is pointing to you words that are likely to be mistakes - and naturally, it's more useful on literary texts than on, say, charters with inventive spelling. Yet... it exists, and it seems to do many people a lot of services).
