The month's weeks should work?
Why 'do' not 'da' ?
Mês is a masculine word, so use "do".
Can "do" mean "of the" in addition to "of"? Could the sentence "As semanas do as mês" also be correct?
Do = de + o (of the) "O" is used for masculine, singular words.
"As" is used for feminine, plural words. De + as = das.
There isn't "do + as".
Why "weeks of the month" is wrong. It should be ok.
You're missing the article
I write "the weeks of the month" and am marked wrong despite that being the right answer. Why?
Now it's correct.
There are days of the week and months of the year but not really weeks of the month, since a month is on average 4.33 weeks.
