The word 固执己见 is formed by combining the two-character term 固执, meaning "stubborn" or "obstinately holding", with the two-character term 己见, meaning "one's own opinion". 固 conveys solidity or firmness, 执 denotes persistence or holding, 己 refers to oneself, and 见 indicates a view or perspective. Together, these characters directly construct the meaning of stubbornly adhering to one's personal views.
