Hi 2teez, thank you very much for your suggestions. The difficult part to me comes when there are multiple misspellings, randomly scattered in the word to be checked against the reference one. In this case, it is crucial to capture sets of variations, which is the reason why I was using an array, to which a new element is appended when a new variation is found. In any case, I might use your code as a starting point to rewrite mine, which compared to yours looks really ugly. Philosophical consideration: The more I work on this script, the more I realize how flexible our brain is in dealing with language, and how difficult is to bring to conscience all the processes involved in this task.
