Czenglish: Can you explain me the difference between lend and borrow?
English: I can explain the difference to you.
Czenglish: So you have to say ‘explain to me’?
English: Yes. You can’t follow ‘explain’ with an object pronoun so you need to add ‘to’.
You explain something to someone.
* If you’re not explaining to someone you don’t need ‘to’.
For example, ‘Can you explain the difference between lend and borrow?’ is OK.
** Lenders give and borrowers take.
