To act 'intentionally' means doing something on purpose, with a specific plan or goal in mind. Think of setting an alarm ⏰ because you want to wake up early. It's a deliberate act, not an accident. It means you've thought about it and decided to do it. It's the opposite of acting impulsively. It implies you have a clear idea of what you want to achieve. Consider a chess player moving a piece strategically.
