The word 反抗 is formed by combining two independent characters, each contributing a core meaning that merges into a new, unified concept. The first character, 反 (fǎn), carries the fundamental idea of "opposite" or "against", establishing a stance of opposition. It is paired with the second character, 抗 (kàng), which introduces the notion of "resisting" or "defying" with active force. Their combination is not merely additive but conceptual, where 反 provides the directional stance (against something) and 抗 supplies the active verb-like energy (to resist), resulting in the complete idea of "to revolt" or "to fight back", embodying a dynamic and purposeful act of opposition.
