This is among the most prolific Latin sources of English words. It appears in numerous prefixed forms, all containing to some extent the underlying meaning element ‘lead’, such as deduce, introduce, produce, and reduce, as well as educate and, in less obvious form, subdue.Its past participle produced aqueduct and ductile [14], not to mention (via Vulgar Latin *ductiāre and Italian docciare) douche [18]. And furthermore it comes ultimately from the same Indo-European source as produced English team, teem, tie, tight, tow, and tug.=> aqueduct, conduct, deduce, deduct, douche, duke, educate, introduce, produce, reduce, seduce, team, tie, tight, tow, tugduct (n.)1640s, "course, direction," from Latin ductus "a leading," past participle of ducere "to lead" (see duke (n.)).
