equivalent ruby request?

[mcjcc]

The Wordnik API documentation doesnt show the equivalent ruby requests. What are the other methods and their options? (e.g. get_random_word, get_etymology)

Also, what's the difference between using Wordnik.word and Wordnik.words because
Wordnik.word.get_random_word and Wordnik.words.get_random_word seem to do the same thing.

Thanks
