| -v | Print all words not literally in the spelling list, as well as plausible derivations from the words in the spelling list. |
| -x | Print every plausible stem, one per line, with = preceding each word. |
| +wordlist | Adds words to the dictionary so next time they are found it does not think that they are incorrect. |
