to defend
🛡️ 捍 = hand 扌 warding off + 卫 = guard; two defend-words stacked for emphasis
捍 carries the hand radical 扌 and means to ward off; 卫 is the guard in 保卫 and 卫兵. Doubling two defend-words makes 捍卫 the emphatic, lofty kind of defending — you safeguard ideals, rights, honor, not just a doorway.
