display, arrange, establish

設 is composed of 言 (speech) and 殳 (weapon). 殳 refers to an ancient polearm that was also used as a ceremonial staff of office for rulers, symbolizing authority and power. When authoritative status is paired with spoken commands, a leader can direct subordinates to arrange, display, institute, or carry out plans—thus using 設 to convey the meanings of setting up, establishing, designing, and instituting.
