Common mistake
Saying 'Can you borrow me...?' when you are the one receiving. Wrong: "Can you borrow me your car?" (correct: Can you lend me your car? or Can I borrow your car?)
Trick to remember it
Think about direction: 'borrow' = the item comes TO you. 'Lend' = the item goes FROM you. Are you receiving? Use 'borrow'. Are you giving? Use 'lend'.
Quick rule
Are you the one who will use the item (receiving it)? Use 'borrow'. Are you the one giving the item for someone else to use? Use 'lend'.
Did you know?
In informal American English, 'loan' is widely used as a verb: 'Can you loan me five dollars?' In formal writing, 'loan' is only a noun and 'lend' is the correct verb. Both are accepted in everyday speech.
