Abstract symbols are representations that convey ideas or concepts without relying on physical forms. They often express emotions, beliefs, or values, allowing for deeper understanding beyond literal interpretations. Examples include mathematical symbols, musical notes, and traffic signs, which communicate specific meanings in a simplified manner. These symbols can vary widely across cultures and contexts, making them powerful tools for communication. For instance, the peace symbol represents harmony and non-violence, while the heart shape signifies love and affection. By using abstract symbols, people can share complex thoughts and feelings efficiently and universally.
