        String the prepared lemma

      • getIndexWordIterator

        pos - The part-of-speech
        Returns:
        An iterator over IndexWords

                                throws JWNLException
        Look up a word in the database. The search is case-independent, and phrases are separated by spaces ("look up", not "look_up"). Note: this method does not subject lemma to any morphological processing. If you want this, use lookupIndexWord(POS, String).
        Parameters:
        pos - The part-of-speech.
        lemma - The orthographic representation of the word.
        Returns:

        Throws:
        JWNLException

        Return an Iterator over all the Synsets of part-of-speech pos in the database.
        Parameters:
        pos - The part-of-speech.
        Returns:
        An iterator over Synsets.
