''Borrow” means that you want to temporarily take something or you're letting someone take something that belongs to you; “borrowed” is the past tense.
“Lend” means you’re giving something to someone or asking someone to give you an item you need; “lent” is the past tense.

• Substitute “take” to check if “borrow” is the right word, and “give” to check if “lend” is the right word.
