Lately ive been hearing people using Learn/Taught in my opinion the wrong way, for example i watched a video of a woman using a circular saw and it caught her jumped and wrapped itself up in it, then the video cut to a guy and he said "That'll learn ya!", but i would say that "That'll teach ya" My partner and her family use it the wrong way aswell. Other instances people using Borrow/lend the opposite way round.
