Cultural appropriation is when someone from one culture takes ideas, symbols, or styles from another culture without really understanding or respecting the original culture. For instance, if someone wears traditional clothes from another culture or uses music or language from a different culture and they don't know the true meaning and significance of those items, it can be seen as disrespectful and hurtful. Imagine if someone was wearing clothes that had great significance to a particular group but they didn't understand what it meant. That wouldn't be very nice.
