I’m slowly battling my way through course 2, and up to lesson 17, and noticed a new structure which seems to have the same meaning as we used to have in course 1.
Here’s an example (please excuse my Welsh spelling!)
Dwi angen ymarfer.
Mae angen i me ymarfer.
Perhaps I’m over-thinking this, but aren’t these interchangeable, or are certain situations where one is more appropriate than the other?
