Scaredy-cat is a popular term used to describe someone who is timid and easily frightened. However, there are a number of antonyms that can be used to describe someone who is brave, courageous, and fearless. Some of the most common antonyms include fearlessness, bravery, boldness, confidence, and daring. These are all qualities that reflect a willingness to take risks and face challenges head-on, rather than avoiding them out of fear. So, instead of calling someone a scaredy-cat, try using one of these antonyms to help encourage bravery and confidence.
