Let's find some missing words. Here's an example: eat : feed :: drink : ? Notice that there's no word (that I know of) for giving someone a drink and having them drink it, in the same way there's a word for giving someone food and having them eat it. There might be some fancy word of Latin or Greek origin, but notice that the three words given are native words; I'm mainly focusing on native word stock. One might possibly argue that when people are eating, they're usually also drinking, so there's often no need for such a distinction. But I don't think it can be explained away this easily. If anyone can think of missing words, I'd like to see them. I'm also interested in knowing if there are languages that have these missing words in their own word stock. I'm especially interested in how Esperanto handles them, since it's apparently a very logical (and I assume consistent) language as far as word construction.
