Origin

Unadapted borrowing from French dérailleur, from dérailler (“to derail”) + -eur (suffix forming masculine agent nouns from verbs). Dérailler is derived from dé- (prefix meaning ‘away; from; off’) + rail (“rail”) (ultimately from Proto-Indo-European *h₃reǵ- (“to righten; to straighten”)) + -er (suffix forming infinitives of first-conjugation verbs). Doublet of derailer.
