Many a folksong contains obscure words or expressions and there have been threads about this at times. It may be dialect, jargon, archaic words, local (in time or place)expressions or forgotten sexual euphemisms. Whatever it makes some songs quite unintelligible. What are "chain plates"; what is Lead Belly song "Pigmeat" about; what does "Stooin Doon The Waall" mean? Could a glossary of terms be started rather like the biographies and the database? Dr John.
