"I don't like the word 'addict' because it has terrible connotations," Root says one day, as they are sunning themselves on the afterdeck. "Instead of slapping a label on you, the Germans would describe you as Morphiumsuchtig. The verb suchen means to seek. So that might be translated, loosely, as 'morphine seeky' or even more loosely as 'morphine-seeking'. I prefer 'seeky' because it means you have an inclination to seek morphine."
"What the fuck are you talking about?" Shaftoe says.
"Well, suppose you have a roof with a hole in it. That means it is a leaky roof. It's leaky all the time - even if it's not raining at the moment. But it's only leaking when it happens to be raining. In the same way, morphine-seeky means that you always have this tendency to look for morphine, even if you are not looking for it at the moment. But I prefer both of them to 'addict', because they are adjectives modifying Bobby Shaftoe instead of a noun that obliterates Bobby Shaftoe."
