Warped is the past participle of warp (from Old English weorpan 'to throw, cast', from Proto-Germanic *werpaną), used adjectivally. In current use it is an adjective meaning "twisted out of true shape, or perverse and distorted in outlook". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The history is mainly one of transmission into English, with the older form and sense carried through borrowing or adaptation. The historical chain includes Old English weorpan and Proto-Germanic *werpaną. Related English forms include warp. For dictionary purposes, the important point is the continuity between the older form, the route into English, and the present lexical sense.
