The word 抓走 is formed by combining the character 抓, meaning 'to grab' or 'to catch', with the character 走, meaning 'to go' or 'to leave'. Together, they create a compound verb where 抓 denotes the action of seizing, and 走 acts as a directional complement indicating that the seized object or person is taken away, resulting in the meaning 'to seize and take away'.
