How to exclude hyphenated words with get random words?

[gma...@gmail.com]

Hi, 

I am using the get random words call for a hangman game. I don't want any hyphenated words, is there a way to exclude these?  I don't see a specific option for this in the 'exclude part of speech' setting. For example  "best-organised", "lightning-conductor",  or "parent-cell"  should not be included in my return. 

Thanks
