How to pick a random english word from a list

Question

What would be the best way to go about getting a function that returns a random English word (preferably a noun), without keeping a list of all possible words in a file before hand?

Answer 1

Word lists need not take up all that much space.

Here's a JSON wordlist with 2,465 words, all nouns. It clocks in at under 50K, the size of a medium-sized jpeg image.

I'll leave choosing a random one as an exercise for the reader.
