An obelisk is a tall stone pillar that rises to a point at the top, usually with four flat sides是一種高高的石柱，頂端收尖，通常有四個平面 Ancient Egypt made the famous ones, often cut from a single piece of stone and covered in writing古埃及做出了最有名的那些，通常是從一整塊石頭鑿出來，上面刻滿文字
Later cities copied the shape as a monument — a marker to remember a person or an event. You may have seen pictures of a very tall one in Washington, or one standing in a square in a European city, sometimes brought from Egypt.
Later cities copied the shape as a monument — a marker to remember a person or an event後來的城市模仿這個形狀做成紀念碑——用來紀念一個人或一件事的標誌物 You may have seen pictures of a very tall one in Washington, or one standing in a square in a European city, sometimes brought from Egypt你可能看過照片，像是華盛頓那座很高的，或是歐洲某個城市廣場上的一座，有時候是從埃及運來的
Though actually, not every pointed monument is an obelisk in the strict sense. The true shape is a tall, four-sided shaft with a small pyramid only at the very top — not a church , and not a pyramid, which is wide at the bottom and all . The word is rather specialist; everyday English might just say that tall pointed monument.
