Note: Use of this word in its most predominant modern meaning is attested early in legal Anglo-French and British Medieval Latin, though the precise derivational pathways are uncertain. The Latin word may have been based on the Anglo-French word, but both must ultimately be dependent on the classical Latin verb. Note that rapum exists alongside classical Latin raptus, the regularly derived u-stem verbal noun, used in British Medieval Latin in the sense "rape." Compare ravish.

Note: The verb rapen in its predominant modern sense is rare in Middle English, the more common verb meaning "to rape" being ravisshen "to ravish." The Middle English Dictionary lists rapen with a meaning "to carry off, transport (the soul to heaven)," but all forms cited are for a past participle rapt, rapte, which appears to have been borrowed directly from Medieval Latin raptus, past participle of rapere in this sense (see rapt). See also the note at rape entry 1.

Note: The Greek forms with fluctuating aspiration, as well as the derivative rháphanos "any of various cultivars of Brassica oleracea, radish," with the suffix -anos, argue for membership in the same pre-Greek substratum as a number of other Greek words; whether the other European forms are borrowed from this etymon or are part of a more general substratum is unclear (see Robert Beekes, Etymological Dictionary of Greek, Brill, 2010, p. 1277). Not related to Old Norse rófa "tail" (see Guus Kroonen, Etymological Dictionary of Proto-Germanic, Brill, 2013, p. 415).
