"on" is correct and is also used in North America, the mistake is probably the tense of "wait"you used. Or maybe Duolingo didn't expect "telephone" in the sentence.
The tense is okay. You are probably right that "telephone" was not expected. I feel that should be reported and corrected.
In most of the US, you'd say "wait for" rather than "wait on his call." I'm not sure about British English, though.
"I wait for him to call" also not accepted for some reason. Perhaps slightly different tense?
While that is more likely what you would say in English, telefoontje is being used as a noun here.
For Dutch mother tongues: Is this really used a lot? Netiher in German, nor in English, it is not that common at all...
yes, telefoontje means phone call, whereas just telefoon would mean telephone. Many diminutives have different meanings from the normal word.
"I am waiting for his call" is very common in English. [Native US English speaker]
Sure, what I meant is the diminutive. "Telefonaatje" is a strange word somehow.
Noone ever says "I am waiting for his callsie" (or whatever diminutive you might use in English). Or in German "Ich warte auf ihr Telefonatchen".
In the tips notes of section, at the bottom it says: "Many diminutives obtain different meaning" Het telefoontje= phone call, and het ijsje=icre cream (instead of meaning little ice)
just a comment: in Spanish diminutives are also used quite a lot (cervecita, asadito, partidito, etc.) and at least where I live it is not uncommon to hear ppl say that they need to make "un llamadito" when they need to make a phonecall.
That's right, and we have to say that those diminutive forms adds a familiar tone, making the action less formal, or in some cases it add an ironic meaning. I think it's the same in Dutch, nevertheless there are words with another meaning when they are used in diminutive form.
it depends on the area. In my area we refer to phonecalls as masculine (un llamado telefonico -sorry, my keyboard is screwed up), therefore the diminutive would be "llamadito" :)
Yet, really informal (slang most likely) but I've heard in latin Spanish "échame un fonazo". Like "drop me a 'phone" to ask someone to call you.
I don't think it's slang. And in my experience 'échame in fonazo' is not common in Latin American Spanish in general, but it's rather restricted to certain areas/countries.
British English would prefer. 'I am waiting for his phone call' rather than, 'I am waiting for his call', although the latter is acceptable'.
Take the 'Ch' from 'Chess' the use the 'e' from 'jongen', that's what it sounds like
