Cryptonomicon ch.43 morphium addict vs. morphium seeky

Cryptonomicon by Neal Stephenson
Chapter 43
(excerpt)

"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 ‘Morphiumsüchtig.’ 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 that 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."

"So what’s the point?" Shaftoe asks. He asks this because he is expecting Root to give him an order, which is usually what men of the talkative sort end up doing after jabbering on for a while. But no order seems to be forthcoming, because that’s not Root’s agenda. Root just felt like talking about words. The SAS blokes refer to this kind of activity as wanking.
