rapt (adj.) Look up rapt at Dictionary.com
c.1400, "carried away" (in an ecstatic trance), from Latin raptus, past participle of rapere "seize, carry off" (see rape (v.)). Sense of "engrossed" first recorded c.1500. As a past participle adjective, in English it spawned the back-formed verb rap "to affect with rapture," which was common c.1600-1750. The figurative sense is from the notion of "carried up into Heaven (bodily or in a dream)," as in a saint's vision.
