I have been taught that third person singular can be he, she or you, absent the clarifying pronoun. Why is you marked wrong?
Nobody knows, you are absolutely right, so report it. formal you should be accepted.
Easier to translate as "Will he/she/you want to come with us?" instead of "going to want to come with us". Too many words.
I'm curious about DL translating future tense using "Going" instead of "will".
I suspect that DL may be recycling lessons from other languages. In particular, Spanish has the "ir" future - using "to go" to express the future tense, and perhaps we're seeing that recycling when DL translates clear examples where "will" is appropriate and proper with "is going".
There are two verbs in this sentence: vorrà and venire. Which of these two verbs is the MODAL VERB which this DL lesson is supposed to be about? Survey says? __ (ding ding ding ding: Family Feud bell ringing)
We only have four "i verbi modali" in Italian: dovere, potere, sapere and volere.
Are you sure about sapere ..? In my humble opinion there are only three modal verbs in Italian:
potere (to be able to)
dovere (to have to)
volere (to want to)
"Is he going to want to come with us?" Is this correct English? I have my doubts.
