scan词源中文解释
14世纪晚期， scannen，“按韵律划分诗歌，根据韵律分析诗歌”，源自晚期拉丁语 scandere “扫描诗歌”，最初在古典拉丁语中，“攀登，上升，登上”（联系概念是诗歌的上升和下降节奏），源自 PIE *skand- “跳跃，跳跃，攀登”（源还包括梵文 skandati “匆忙，跳跃，跳跃”； 希腊语 skandalon “绊脚石”； 中爱尔兰语 sescaind “他跳跃，跳跃”， sceinm “一跳，跳跃”）。
英语可能因为与后缀 -ed 混淆而失去了古典 -d-（比较 lawn（n.1））。1857年，不及物动词的意思是“遵循或符合韵律规则”。1540年代记录了“逐点查看，仔细检查（如在诗歌中计算韵脚）”的意义。新技术带来了“系统地用扫描仪扫描”的意义，特别是将其转换为一系列信号（1928年）。1926年记录了“快速查看，略读”的（相反）意义。相关： Scanned； scanning。
