Can mì also be written as mỳ? I feel like I have seen the latter before in previous lessons.
Yes, it can.
mì = noodles + Ý = Italy ... so I guess italian noodles = pasta
Is it also implied that the bedroom belongs to the subject, or does it have to be followed by của mình?
Could it also be "noodles"?
Are trong and ở trong interchangeable?
