Translation:Can I get this watch?
This could also be more directly translated as "Please give me this watch".
It means more or less the same, but I think your translation is extra polite whereas the Japanese is normal polite.
I dislike this translation as the origanal sentence is not a question.
This sentence automatically translates to Can I get this watch please? In my mind. But the please is often omitted, why?
"I want this watch please" was wrong. Is that rude? I know there is no ほしい in the japanese frase, but still.
'I want this watch' is different from 'Can I get this watch' or 'Please give me this watch', so in Japanese I think it would be a different question. Maybe thats why its wrong?
Well, that's not a very literal or conventional way to translate that, but I suppose it would be alright, in the assumed context.
It's probably an American thing, but using "get" to order something doesn't necessarily sound rude to me. "Can I get this black watch in the display case, please?" That said, of course "have" should be accepted as well.
No, the phrase is common among younger Americans. By no means is it ubiquitous.
I agree that it's not the best answer, but it is certainly used, apparently even in the UK. It's similar to the "can I?" versus "may I?" debate, where both should be accepted but obviously "may I?" is more correct and should be the top answer. That doesn't invalidate the usage of "can I?"
The first batch of questions in this lesson were all pictures+words and solely used the kanji. But all the writing questions don't use any of the kanji it just taught us...
"Can I please have this watch?" should also be correct. "ください" implies "please"
God this sucks. One time it's "can i have", then its "give me" again.. Guys, just accept either one... and also accept it without can or give me! Its frustrating and annoying to study like this.
Japanese is in beta, so unfortunately until someone submits an error report and it is checked for every single possible answer to every single question, there's going to be some oversights and inconsistencies.
When you get a question wrong in the iPhone app, you can click on the word “REPORT” under your corrected answer. If you use the web browser version, there’s a report button after you answer the question. I’m not sure about android.
