Take this word: ‘grok.’ Its literal meaning, one which I suspect goes back to the origin of the Martian race as thinking creatures—and which throws light on their whole ‘map’—is easy. ‘Grok’ means ‘to drink.’”

“Huh?” said Jubal. “Mike never says ‘grok’ when he’s just talking about drinking. He—”

“Just a moment.” Mahmoud spoke to Mike in Martian.

Mike looked faintly surprised. “‘Grok’ is drink.”

“But Mike would have agreed,” Mahmoud went on, “if I had named a hundred other English words, words which we all think of as different concepts, even antithetical concepts. ‘Grok’ means all of these. It means ‘fear,’ it means ‘love,’ it means ‘hate’—proper hate, for by the Martian ‘map’ you cannot hate anything unless you grok it, understand it so thoroughly that you merge with it and it merges with you—then you can hate. By hating yourself. But this implies that you love it, too, and cherish it and would not have it otherwise. Then you can hate—and (I think) Martian hate is an emotion so black that the nearest human equivalent could only be called mild distaste.
