I wonder if she'll meet the guy with the big cucumber.
Bărbatul cu castravetele larg și tare.
Let's hope so. ;)
Why is it două in this situation?
apple is feminine
If by feminine you mean neuter then you're right. Curiously the same word (măr) is also used for apple tree but then it's masculine. Go figure.
Femeia are ,,doua'' mere moi. Means that she has ,,two'' soft apples she doesn't have an/one apple she has two and doua is used in this situation because she doesn't have one, she has two soft apples.
Hope this helped you!
