Designed
指有目的地规划外观、结构或流程；被动式 “be designed to” 引出功能目标。也可形容图案或风格（“a beautifully designed app”）。
- “The bridge was designed to withstand strong winds.” (这座桥的设计能承受强风。)
- “She designed a logo for the local bakery.” (她为本地面包店设计了一个标志。)

“Design” 源自拉丁语 “dēsignāre”（标记、指定），由前缀 “de-” 与 “signum”（记号）组成，与 “sign” 有历史联系。
过去分词 “-ed” 规则变化；前缀 “de-” 在词源层表示加强标记，现代语义已整体化为“设计”。
科技产品发布会常用 “newly designed hardware”；建筑评论里强调 “human-centered designed spaces”。
- 固定搭配: “designed for speed” (为速度而设计), “custom-designed” (定制的)
词里藏着 “sign”——先在纸上做记号，再把这些记号变成蓝图。
“The backpack was designed with hidden pockets for travel documents.” (这款背包设计了隐藏口袋来放旅行证件。)
