enthralling
UK: ɪnˈθrɔːlɪŋ | US: ɪnˈθrɔːlɪŋ
adj. capturing and holding one's attention completely; fascinating or spellbinding.
The word "enthralling" originates from the Old Norse þræll (slave), which evolved into Middle English thrall (a person in bondage). The prefix en- (from Old English in-) implies "causing to be in a state," while -ing forms the adjective. Thus, "enthralling" literally means "putting someone into a state of bondage"—metaphorically describing something so captivating it feels like mental or emotional enslavement. Over time, the negative connotation faded, leaving only the sense of irresistible fascination.
