Explanation
If you're undaunted, you're not afraid or intimidated. As a great surfer, you remain undaunted as you seek out dangerous waters to ride the biggest waves. The adjective undaunted was first used in the mid-15th century to describe horses that were "untamed, not broken in." These horses must have seemed wildly fearless and intrepid even in the most difficult situations. Similarly, an undaunted person remains courageous and bold when facing fear, difficulty, and danger. Paramedics and firemen are undaunted when faced with a burning building. You must remain undaunted when facing your terrifying calculus homework.
