pelf

In the late Middle Ages, the Anglo-French word pelfre, meaning "booty" or "stolen goods," was borrowed into English as pelf with the added meaning of "property." (Pelfre is also an ancestor of the English verb pilfer, meaning "to steal.") Eventually, pelf showed gains when people began to use it for "money" and "riches." In some regions of Britain the word's use was diversified further, in a depreciative way, to refer to trash and good-for-nothings. The first of those meanings was a loss by about the mid-17th century; the second has little value outside of the Yorkshire region of England.
