lag

英 [læɡ] 好意思 [læɡ]

v.过期；减退；安逸进行 n.过期；时刻绝交

◉词源

Lag 于16世纪早期（约1520s）出现，看成动词意为“安逸转移、过期、跟不上模式”。最早看成名词（1510s）指“终末的东谈主、过期者”（last person），描写词（1550s）指“渐渐的、过期的”。发源不祥情，可能来自斯堪的纳维亚语源（如挪威方言 lagga “安逸行走”），或与 last/lack/delay 的方言变体干系。从“终末又名/过期者”→“动作/发展安逸过期”（动词，1530年起）→当代多义：时刻延长（如 jet lag， time lag）、技巧延长（如汇集 lag）、经济/性能过期（如 lag behind）。

The word lag describes a kind of slowness or delay. As a noun， it means a slowing: "The coach was disappointed by the lag in her swimmers' best times that day." When you lag behind someone， you fall back or don't measure up. A student who struggles with math， for example， might say that his grades lag behind his best friend's. In the 1550s， lag meant "last person."
