A pioneering spirit means being brave and taking risks to try new things.
When we call someone or something "pioneering", we usually mean they are doing something that hasn't been done before. Maybe a company is developing a brand-new product, like a self-driving car, which people have never seen before. Or maybe a person is starting a charity that helps in a way no one has tried before. It's often used to describe things that are innovative and groundbreaking.
To be the first to do or achieve (something), preparing the way for others to follow.
Example: The young doctor pioneered a new life-saving surgical technique.
The activity of the verb pioneer.
Involving accomplishments or activities that have not been done before, or developing or using new methods or techniques.
Example: Norway as a polar nation would not have been what it is today without their tireless pioneering efforts. [Roald Amundsen and Fridtjof Nansen]
