Etymology

Origin of siege

First recorded in 1175–1225; (noun) Middle English sege, from Old French: “seat,” noun derivative of siegier, from unattested Vulgar Latin sedicāre “to set,” derivative of Latin sedēre “to sit” ( see sit ¹); (verb) Middle English segen, derivative of the noun

Explanation

Your city is under siege if it is surrounded on all sides by an opposing force on attack. Think of a castle surrounded by a legion of armed knights. Like many military words, siege can be used metaphorically. If you start getting thousands of e-mail messages trying to sell you canned meat, you might feel like you're under a siege of spam selling spam. In this case, you have been besieged by spam. And even more unfortunately, if you are having a siege of bad luck, you have been besieged by bad luck.
