What's the Olludith in Dothraki?

In Dothraki, the canonical case role is the nominative-accusative language. But if something is not going to be wholly affected by that action, rather than having to add all this verb-age you can use Olludith instead. And so basically what it does - and here this almost goes back to Gricey and Maxims,. where with Grice's conversational Maxims people expect a certain thing from a conversation. If somebody says something that's counter to what's expected, they have to believe that the person talking to them is saying something relevant.
