pathfinder (n.)

"发现一条路的人，探险家或先驱者"，1839年（库珀），源自 path + finder。

"Pathfinder!"

"So they call me, young woman, and many a great lord has got a title that he did not half so well merit; though, if truth be said, I rather pride myself in finding my way where there is no path, than in finding it where there is. But the regular troops are by no means particular, and half the time they don't know the difference between a trail and a path, though one is a matter for the eye, while the other is little more than scent."

[Cooper, "The Pathfinder"]

"探路者！"

"年轻女士，他们这样叫我，许多伟大的领主得到了他们没有完全配得上的头衔； 虽然，如果说实话，我更自豪于在没有路的地方找到路，而不是在有路的地方找到路。但是常规部队并不特别挑剔，而且有一半的时间他们不知道小径和路径之间的区别，尽管一个是眼睛的事情，而另一个几乎只是气味。"

[库珀，《探路者》]
