carceral

adj

Etymology: From Late Latin carcerālis (“carceral”), from Latin carcer (“jail, prison”) (ultimately from Proto-Indo-European *(s)ker- (“to bend, turn, in the sense of an enclosure”)) + -ālis (suffix forming relational adjectives).

1. Of or pertaining to imprisonment or a prison.

   “[O]n his showing signs of penitence, through favour they were contented that he should be released from his carceral endurance, in case he would put in sufficient surety in the king's chancery, and swear that he would never hold or favour any such opinions hereafter. And so, taking an oath of him, the archbishop committed him to the custody of the bishop of Worcester, to whom power and authority were permitted to release him, upon the conditions aforesaid.”

   “This moon-calf of the imagination binds your reason, sir, in carceral chains.”
