"The eraser of the pencil is small."
Translation:Guma de șters a creionului este mică.
Why do I have to say ”a creionului”? The first suggestion from the hover translation was simply ”creionului” and I thought that was enough...
I cannot explain why, but it seems that if you would choose to say guma creionului then you should not be using an a. However, saying guma de șters a creionului requires that you use an a.
It could be. If I think of similar scenarios like
- Mașina bărbatului e albastră. (The man's car is blue.)
- Mașina de cusut a bărbatului e albastră. (The man's washing machine is blue.)
it follows your rule.
i have read that after an adjective you have to use Al. Ai, A, Ale... there are some rules to follow, oyu can download Romanian An Essencial Grammar, there is more explained.
