intrepid
Very brave and not afraid to face great danger.
Intrepid means fearlessly brave, especially when facing danger or exploring the unknown. An intrepid explorer ventures into unmapped jungles or climbs treacherous mountains, pushing forward despite real risks. An intrepid reporter investigates dangerous stories that others avoid.
The word suggests more than ordinary courage. Someone might be brave enough to give a speech in front of their class, but intrepid describes the kind of bold fearlessness needed for truly daunting challenges: sailing across an unknown ocean, standing up to powerful wrongdoers, or attempting something never done before.
Intrepid adventurers like Amelia Earhart, who flew solo across the Atlantic Ocean, or Ernest Shackleton, who led Antarctic expeditions through brutal conditions, embodied this quality. They faced genuine danger but refused to let fear stop them from pursuing their goals.
You might read about intrepid pioneers who settled new lands, intrepid scientists who test their theories in extreme environments, or even an intrepid student who volunteers to perform first at the talent show. The word celebrates the kind of courage that drives people to do difficult, sometimes dangerous things because they believe the goal is worth the risk.
