Definition of shackle

The word "shackle" derives from the Old Norse word "hakla," which means "a fastening," "a hook," or "a clasp." This word was brought to England by the Viking invaders in the 9th century, and it had already gained a negative connotation by then, as it referred to the iron restraints used by the invaders to secure captive prisoners. The Old English word "hacel" (or "hcаcel"), which was derived from the Old Norse word "hakla," was also used to describe such captivity devices, but it eventually fell out of use. Over time, the Old Norse word "hakla" evolved into its modern English equivalent, "shackle." This word has been used to refer to various devices for restraining people, animals, or objects, such as leg irons, chains, and handcuffs. Its origins in the Old Norse language and its association with Viking invasions and captivity have given it a strong connotation with oppression, confinement, and restriction. In modern usage, shackle most often refers to the chains that are used to tie prisoners together or to fixed objects, such as trees or walls, in order to prevent escape or to punish captives.
