A balustrade is a row of posts — wood, stone, or metal — with a rail along the top, built at the edge of a balcony, bridge, terrace, or staircase so nobody falls. The single posts are balusters; the whole row plus the rail is the balustrade. Architects and house descriptions like the word; in everyday talk people often just say . Though actually, a plain metal fence is not usually called a balustrade — the word still carries a picture of those upright posts, once thought to look like a half-open flower. English took it as-is from French, and French from Italian.
欄杆（較精準指一排欄杆柱加上扶手；建築上也說寶瓶欄杆）
組成Unadapted borrowing from French balustrade, from Italian balaustrata (“with balusters”), from balaustro (a baluster), from the word for a wild pomegranate flower — because the swelling post was thought to look like that half-open flower.
