extravagant

An extravagant person or thing is one that shows no care for money and goes over the top with spending or doing something.

Think about it like this: when someone describes a party as "extravagant", they probably mean it was super expensive, had way too much food and decorations, and maybe even some weird or over-the-top entertainment. For example, if you attended a wedding where the couple hired a 20-piece band to play for hours, spent thousands on designer flowers, and served champagne instead of the usual sparkling cider, that's probably an extravagant celebration.

The word "extravagant" can also mean something that is extremely good or excellent in quality. In this case, it describes someone who has a lot of talent or skills, like an actor who gives an extravagant performance (meaning one that's impressive and over-the-top).
