DL hasn't taught "num" before now! Sucks that I got it wrong .
and why is it em um or num instead of no?
no = in the / num = in a
Is num used in contemporary Portugese?
Indeed, all the time!! Not the same for dum (de+um) and duma (de+uma).
Why is there a 1 in answer?
even though you asked this question 2 years ago, duolingo will sometimes correct "the" to "a" by saying you only need (1) in your answer
i translated it as ''num campo" The owl says it's correct but writes "em um campo" Which of the 2 would be Portuguese portuguese?
Duo translates it as 'em um campo' instead of num campo. I always thought using construction em + um/uma is incorrect and it should be always num or numa, isnt it?
Some contractions are not mandatory. You can use "em um/uma".
