I had lend 500$ from kelly.
I had Borrowed 500$ from kelly.
The above sentences are correct or wrong.
The first is certainly wrong, because the past participle of the verb “to lend” is LENT (irregular verb) and because “to lend” means that you give another person something for some time, so you don’t lend FROM SOMEBODY but you lend SOMEBODY.
Hi swami 
The meaning of the word ‘lend’ is similar to the word ‘give’:
You can ‘lend something to’ and you can ‘give something to’, BUT you cannot ‘borrow something to’.
The meaning of the word ‘borrow’ is similar to the word ‘take’:
You can ‘borrow something from’ and you can ‘take something from’ BUT you cannot ‘lend something from’.
Does that help?
Amy
I agree. We use “lend” to signify giving and we use “borrow” to signify taking. The owner can lend you something and the borrower can only borrow or take what the owner lends him.
If I’m lending you my book, you are taking my book. By doing so, you are borrowing the book from me.
