The Chinese word 障碍物 (zhàng'ài wù), meaning "obstacle" or "barrier," is a compound noun formed through morphological derivation. It begins with the disyllabic verb 障碍 (zhàng'ài), which itself is a compound meaning "to obstruct" or "to hinder," composed of two synonymous characters (障 and 碍) that reinforce the core concept of blocking. To this verbal root, the suffix 物 (wù), meaning "thing" or "object," is added, thereby nominalizing the verb and specifying a tangible entity that causes obstruction. Thus, the formation follows a clear semantic logic: a "thing" (物) that "hinders" (障碍).
