spend a fortune

Grammar-wise, this phrase is a heavy lifter. The most common structure is spend a fortune on [something]. Notice the preposition on. Many people mistakenly use for or in, but on is the king here. You can also use it without a target if the context is clear. For example, "I went to the mall and spent a fortune." We don't know what you bought, but we know your credit card is crying. You can add modifiers to make it even more intense. Spend a small fortune is a funny English quirk. Even though a 'small' fortune sounds like less, it actually sounds more precise and often even more expensive in a weird, sarcastic way. It’s like saying, "It wasn't a million, but it sure felt like it."

Think about your last vacation. You probably spent a fortune on flights, hotels, and those tiny bottles of water in the hotel fridge.

One of the biggest traps is the preposition. ✗ I spent a fortune for my car. → ✓ I spent a fortune on my car. Another mistake is trying to make fortune plural. ✗ He spent many fortunes.

Also, don't confuse it with cost a fortune. While they are related, spend is the action you take, while cost is the price the item demands. You spend a fortune, but the house costs a fortune.
