There are some dubious examples of English usage in the section on verbs. I understood what was intended but only because I am already well familiar with the topics the author intended to illustrate. > However, there is something funny about transitivity: some verbs, like "walk", you can only use intransitively (we don't say that we "walked the street", for instance), but many verbs can be used either intransitively or transitively, like "eat". One can "walk the streets of Bakersfield". > For instance, traversal verbs (such as 'walk', 'run', 'fly', 'sail', etc.) are intransitive in English, but ... while in English one does not "fly the sky" or "swim the ocean" (at the very least you'd need a preposition such as "through" or "in" to make those correct English), in Japanese this is exactly what you're doing. Although we don't often say that someone swam the ocean, Columbus "sailed the ocean blue".
