掲げる
かかげる · kakageru · JLPT N1 · verb-ichidan
to hoist
🚩 掲 has the hand radical 扌: raise it high with your hand, as you would a flag
掲示板 (noticeboard) is a board where notices are hung up high. 掲げる is the verb for raising a flag or banner aloft, so the same kanji root carries the idea of lifting something up.
