Wroth means very angry, furious, or wrathful. It's archaic past participle of "writhe" used as adjective, suggesting anger that makes one writhe or contort. Medieval romances use wroth for powerful anger: "
The king grew wroth." Students should recognize wroth as stronger than "angry"—it suggests fury or rage. In Old English and Middle English, wroth appears frequently in descriptions of offended nobles or wrathful gods. The phrase "wax wroth" means become angry (wax = grow, become). Etymology from Old English wrath (angry), related to "wrath" (noun for anger).
Shakespeare uses wroth in elevated contexts: "He was wroth" sounds more serious than "He was angry." Understanding wroth's intensity helps gauge emotional registers in texts. Compare "angry" (standard), "irate" (formal anger), "wrathful" (divine or terrible anger), and "wroth" (archaic, intense anger). By the 18th century, wroth was declining except in poetry and biblical language. Modern usage preserves "wrath" (noun) more commonly than "wroth" (adjective). In fantasy and historical literature, wroth signals archaic diction and often precedes violent action. The term's harsh sound reinforces its meaning of intense, potentially dangerous anger.
