You have to know the inflections to code them. For a mobipocket dictionary, you have to follow the documentation given here:
http://www.mobipocket.com/dev/articl...e=indexing.htm. It requires a lot of extra HTML coding. A .prc file should be about the same as a .mobi file, usually. .mobi would be preferred. I don't know if a Kindle, for example, would allow a dictionary with a .prc suffix. The dictionary would not be tab-delimited, but all in HTML.
Tab-delimited format is where each field is separated by tabs. Sometimes the text fields are quoted, in addition. There can be issues if the text field has newlines or tabs in it. Not sure what the rules are for that. Google is your friend. Maybe you use backslash quoting for things like that, like \t instead of tab, \n instead of newline, etc., depending on what is going to be reading the file.
