"You have the twentieth."
Translation:Tu ai a douăzecea.
The numbers 1, 2 and 12 have forms for feminine and masculine (for 12 - doisprezece and douăsprezece). While 20 has only one form (douăzeci). So:
al doisprezecelea (12th, masculine)
a douăsprezecea (12th, feminine)
al douăzecilea (20th, masculine)
a douăzecea (20th, feminine)
Thanks for the clarification Enchom! I don't know if there is some logic behind this, guess I will just have to learn those irregularities.
The grammatical logic is: doisprezece and douasprezece literally mean "two and ten" which leaves the "two" subject to the gender of whatever it relates to. Kind of like "doi si zece baieti". douazece literally means "two tens", meaning that the "two"'s gender relates to "tens" which is feminine, regardless of the context.
