The word 不怕 is formed by directly combining the character 不 (bù), which means "not", with the character 怕 (pà), which means "to fear" or "afraid". It is a simple, logical construction where the negation is placed directly before the verb or state it modifies, creating a single conceptual unit that means "not afraid" or "fearless". This formation follows the fundamental and intuitive pattern in Chinese where 不 is prefixed to a verb to create its opposite meaning.
