Some challenges (that I'm currently mulling over with a view to posting) require that the solution produces valid words. Having to embed an entire dictionary in a code-golf entry isn't the point of the challenge, so I'd like answers to be able to depend on access to a word list.
It doesn't matter if answerers don't all have the same list of words, as long as they select only words from the list. Test cases can be given with a small wordlist, for verification of results.
Is there a standard phrase I can use in a question to indicate that answers don't have to embed their own word lists? And if the question doesn't contain any such phrase, what should answerers assume when they need a word list?
