- paleologism
-
Word or phrase that was coined in the distant past, often now obscured, or if recently used: possibly having a definition or implication different from that of any earlier usage.
Another is the paleologism of pars pro toto in which a part of an organ or function can symbolize the whole organ or concept; eg, the stomach may be the locus of difficulty with a patient with a history of frustrated dependency needs because of its association with the process of being fed and loved by the mother.
