鉛筆
えんぴつ · enpitsu · JLPT N5 · noun
pencil
✏️ 鉛筆 = lead (鉛) + writing brush (筆): a lead brush
鉛 (en) means the metal lead, and 筆 (hitsu, voiced to pitsu after n) means writing brush. Early pencil cores were mistaken for lead, so Japanese named the tool a lead brush, just as English still says pencil lead.
