"I travel to the US every year."
旅行 is a noun and 旅行する is the verb. Here you need the noun (similar to English actually you can't have 2 verbs in a row).
旅行に行きます (not 旅行するに行きます)
I go travelling
買物に行きます (not 買うに行きます)
I go shopping
食事に行きます (not 食べるに行きます)
I go eating
Am I understanding right that this would be more like saying "I go traveling to the US every year" as a "word for word" translation rather than "I go to the US every year" or "I travel to the US every year"? Basically, we're saying we are "doing the traveling" like we "do the shopping"? (it sounds a bit weird...)
I would recommend a literal breakdown like this:
毎年 / Every year
アメリカへ / to the U.S.
りょこうに / for the sake of traveling
行きます。 / ( I ) go
Would any meaning be lost, changed, or otherwise sound unnatural by losing the 行く and using the する form of 旅行?
I think it's just something like "I travel in US" and "I go travelling in US", not much actual difference.
Couldn't you replace りょこうに行きます with 行きますand basically get the same meaning? (It's what I did, and it was marked wrong.)
You can, Faisane.
But then you are just saying "I go to the U.S. every year.". We don't know for what purpose you go there.
Yes, traveling for leisure, for an experience, for an adventure, etc. Anyway not just merely displacing from one place to another.
Ok, that makes it clearer - thanks. (Fwiw, I don't think "travel to the US" captures the essence, then.)
I agree. It's sounds a bit or at least it could imply business. "I visit the US every year" sounds more like vacation travel.
Typically へ emphasises the movement verb and に emphasises the destination. If you were perhaps having a conversation about the fact you'll be away soon rather than where you will be, then へ might be more appropriate. e.g. "I won't be going to the party, every year around that time I travel to the US."
Both should be correct, although I also wonder if it's considered better style to use へ because you're stating the purpose of に行きます.
So it's the difference between; "I travel to the U.S. every year" being に vs "I travel (to the U.S.) every year." being へ?... Yeah, there is no clean way to really convey that in English over text. They really should either change the sentence to add the parentheses ( or possibly commas ) or they should accept に as a correct answer.
