to be very expensive · to cost a lot of money
Ever seen something you *really* want, but then you check the price tag and your jaw drops? 😱 This expression is perfect for those moments when an item is so incredibly expensive, it feels like you'd have to sell off parts of yourself to afford it! 😂 (Don't worry, it's just a funny exaggeration!)
When would you most appropriately use 'to cost an arm and a leg'? A. 🏷️ When you are trying to describe a very affordable item to a friend. B. 💸 When you are shocked by the high price of a luxury car you saw. C. 💰 When you are discussing how cheap a pair of socks was.
💡 **Pro-Tip!** This idiom is often used with 'it' or 'that'. For example, 'That new smartphone *costs an arm and a leg*!' or 'Buying a house in this city *costs an arm and a leg*.' It's a vivid way to exaggerate the high cost, so people immediately understand it's seriously pricey! 💰
