Lend and borrow

Today I will teach you about two new verbs. The verb LEND and the verb BORROW. Both verbs mean EMPRESTAR. When you need something borrowed from someone you should use the verb BORROW. I will explain the grammar:

1° May
2° Pronoun I
3° Borrow

Examples:

May I borrow a notebook? / May I borrow your notebook?
May I borrow a pen? / May I borrow your pen?

Never! I said NEVER use this grammar with LEND.

So, May I lend a book ? it's completely wrong!

So, How can I use Lend?

Pay attention on the following example:

Can you lend me a book?

As you can see, you should use May I borrow or Can you lend me ...Ok?
