Translation:Ik wil aardrijkskunde studeren.
Why not "Ik wil OM aardrijkskunde TE studeren"? If it's wrong, what would it roughly translate to in English?
It is wrong. We don't use 'om te' with the verb 'willen'. You can't translate it into English, because there is no 'om' in English (not in these type of sentences).
Understood, thanks for the prompt reply!
