I was marked wrong with "He wants gifts". The correct answer was given as "He wants a gifts", which is poor English. Reported 29/4/2017
Reported again 10/9/2017
how do you say "he wants gifts"? (plural)
That is also "Anataka zawadi", because "zawadi" is both singular and plural (noun class 9/10).
If that was the answer you gave and it was still rejected, report it next time you see it. When I gave that answer recently it was accepted.
