The oily oleaginous slipped into English via Middle French oleagineux, coming from Latin oleagineus, meaning "of an olive tree." Oleagineus itself is from Latin olea, meaning "olive tree," and ultimately from Greek elaia, meaning "olive." Oleaginous was at first used in a literal sense, as it still can be. An oleaginous substance is simply oily, and an oleaginous plant produces oil. The word took on its extended "ingratiating" sense in the 19th century.
