unafraid
Not scared to face something hard or frightening.
Unafraid means not feeling fear or being willing to face something scary or difficult without letting fear stop you. When you're unafraid, you might still notice danger or difficulty, but you don't let worry control your actions.
A student might be unafraid to ask questions in class, even when others stay silent. A young inventor might be unafraid of failure, trying again after each mistake. Someone unafraid of heights might climb to the top of the rock wall at recess while others watch nervously from below.
Being unafraid doesn't mean being reckless or ignoring real dangers. It means you've decided that what you're trying to accomplish matters more than your fear. A swimmer who's unafraid of deep water has either conquered that fear through practice or never had it in the first place, but they still respect the water's power and swim carefully.
You might also hear someone described as unafraid to speak their mind or unafraid of hard work. In these cases, the word suggests confidence and determination. The person knows something might be challenging or uncomfortable, but they're willing to face it anyway.
